Combine the Tegra USB header file into one header file for all SoCs.
Use ifdef to account for the difference, especially Tegra20 is quite
different from newer SoCs. This avoids duplication, mainly for
Tegra30 and newer devices.

This commit changes the working directory
where the build process occurs.
Before this commit, build process occurred under the source
tree for both in-tree and out-of-tree build.
That's why we needed to add $(obj) prefix to all generated
files in makefiles like follows:
$(obj)u-boot.bin: $(obj)u-boot
Here, $(obj) is empty for in-tree build, whereas it points
to the output directory for out-of-tree build.
And our old build system changes the current working directory
with "make -C <sub-dir>" syntax when descending into the
sub-directories.
On the other hand, Kbuild uses a different idea
to handle out-of-tree build and directory descending.
The build process of Kbuild always occurs under the output tree.
When "O=dir/to/store/output/files" is given, the build system
changes the current working directory to that directory and
restarts the make.
Kbuild uses "make -f $(srctree)/scripts/Makefile.build obj=<sub-dir>"
syntax for descending into sub-directories.
(We can write it like "make $(obj)=<sub-dir>" with a shorthand.)
This means the current working directory is always the top
of the output directory.

__pinmux_nand() won't compile if PERIPH_ID_NDFLASH isn't defined.
Prevent this from causing build problems on newer SoCs without NAND
support (or without SW support for NAND yet), but preventing
compilation unless the function will actually be used, i.e. when
CONFIG_TEGRA_NAND is defined.

If timer_init() is made a weak stub function, then it allows us to
remove several empty timer_init functions for those boards that
already have a timer initialized when u-boot starts. Architectures
that use the timer framework may also remove the need for timer.c.

We have converted all makefiles needed to build $(LIBS).
Until this commit we used to grep switch so that U-Boot style

But we do not need any more.

As suggested by Stephen Warren, use tegra_get_chip() to return
the pure CHIPID for a Tegra SoC (i.e. 0x20 for Tegra20, 0x30 for
Tegra30, etc.) and rename tegra_get_chip_type() to reflect its true
function, i.e. tegra_get_chip_sku(), which returns an ID like
TEGRA_SOC_T25, TEGRA_SOC_T33, etc.

This moves the Tegra USB implementation into the drivers/usb/host
directory. Note that this merges the old
/arch/arm/cpu/armv7/tegra20/usb.c file into ehci-tegra.c. No code
changes, just moving stuff around.
v2: While at it also move some defines and the usb.h header file to make
usb driver usable for Tegra30.
NOTE: A lot more work is required to properly init the PHYs and PLL_U on
Tegra30, this is just to make porting easier and it does no harm here.

Add driver for tegra SPI "SLINK" style driver. This controller is
similar to the tegra20 SPI "SFLASH" controller. The difference is
that the SLINK controller is a genernal purpose SPI controller and the
SFLASH controller is special purpose and can only talk to FLASH
devices. In addition there are potentially many instances of an SLINK
controller on tegra and only a single instance of SFLASH. Tegra20 is
currently ths only version of tegra that instantiates an SFLASH
controller.
This driver supports basic PIO mode of operation and is configurable
(CONFIG_OF_CONTROL) to be driven off devicetree bindings. Up to 4
devices per controller may be attached, although typically only a
single chip select line is exposed from tegra per controller so in
reality this is usually limited to 1.
To enable this driver, use CONFIG_TEGRA_SLINK

For Non-Nvidia boards to include newly added features (like emc clock
scaling) it would be necessary to add each feature to their own board
Makefile. This is because currently the top Makefile automaticly includes
these features only for Nvidia boards.
This patch adds a simple Makefile include so all new features become
available for non-Nvidia board vendors.

Rename board provided gpio_config_uart() to
gpio_early_init_uart() as it does the same thing as the equally
called function provided by the uart-switch code. This allows
to simply call this function in early board init whether or not
we are building with CONFIG_UART_SWITCH defined.
Also provide a weak symbol for this function, to avoid the
need to provide this function for boards that don't need any
fixup.
This patch supersedes the earlier posted
"tegra: convert gpio_config_uart to weak symbol".

Some files remain in arch-tegra20 but 'include' a file in 'arch-tegra' with #defines & structs
that will be common between T20 and T30 HW. HW-specific #defines, etc. stay in the 'arch-tegra20'
'root' file.

On Seaboard the UART and SPI interfere with each other. This causes the UART
to receive spurious zero bytes after SPI transactions and also means that
SPI can corrupt a few output characters when it starts up if they are still
in the UART buffer.
This updates the board to use the SPI/UART switch to avoid the problem.
For now this feature is turned off since it needs changes to the NS16550
UART to operate.

The Tegra2 Seaboard has the unfortunate feature that SPI and the console
UART are multiplexed on the same pins. We need to switch between one
and the other during SPI and console activity.
This new file implements a switch and keeps track of which peripheral
owns the pins. It also flips over the controlling GPIO as needed
Since we are adding a second file to board/nvidia/common, we create
a proper Makefile there and remove the direct board.o include from
