This moves what was in arch/arm/cpu/armv7/omap-common in to
arch/arm/mach-omap2 and moves
arch/arm/cpu/armv7/{am33xx,omap3,omap4,omap5} in to arch/arm/mach-omap2
as subdirectories. All refernces to the former locations are updated to
the current locations. For the logic to decide what our outputs are,
consolidate the tests into a single config.mk rather than including 4.

Replace the custom bit manipulation function sr32() by standard I/O
accessors. A major motivation for this cleanup was the fact, that a
number of calls of that function resulted in 32 bit wide shift
operations on u32 data, which according to the C-ISO/IEC-9899-Standard
provokes undefined behaviour:
6.5.7 Bitwise shift operators
...
If the value of the right operand is negative or is greater
than or equal to the width of the promoted left operand, the
behavior is undefined.

The only remaining user of the custom bit manipulation function sr32()
is arch/arm/cpu/armv7/omap3/clock.c, so make it a static function in
that file to prepare complete removal.

This patch change the per_clocks_enable() function used in OMAP3
code to enable peripherals clocks. Only required clock should be
activated. So if the board use the uart(x) as a console we need
to activate it. The Board's config should include define to enable
every subsystem that the board use. For a complete list
of affected peripherals, registers CM_FCLKEN_PER and CM_ICLKEN_PER
should be checked.
Right now the bootloader can enable and disable clocks for:
uart(x) using CONFIG_SYS_NS16550
gpio bank (x) using CONFIG_OMAP3_GPIO_X with X = { 2, 3, 4, 5, 6 }
i2c bus using CONFIG_DRIVER_OMAP34XX_I2C.
Not required gptimer(x) and mcbsp(x) for booting are disabled by default and
are not supported by any define.
Their activation need to included in the per_clocks_enable if the
peripheral is included. Not booting board should enable the peripheral
clock connected to their driver

according to errata sprz318e.
In chapter 'Advisory 2.1 USB Host Clock Drift Causes USB Spec Non-compliance in Certain Configurations' of the TI Errata it is recommended to use certain div/mult values for the DPLL5 clock setup.
So far u-boot used the old 34xx values, so I added the errata recommended values specificly for 36xx init only.
Also, the FSEL registers exist no longer, so removed them from init.
Tested this on a AM3703 board with 19.2MHz oscillator, which previously couldnt lock the dpll5 (kernel complained). As a consequence the EHCI USB port wasnt usable in U-Boot and kernel. With this patch, kernel panics disappear and USB working fine in u-boot and kernel.

In warm reset conditions on OMAP36xx/AM/DM37xx the rom code
incorrectly sets the DPLL4 clock input divider to /6.5 which
is an invalid value unless the input clock is 13MHz. When a JTAG
emulator is attached, a warm reset is necessary after the emulator
gains control of the process. This results in a loss of serial
output due to the invalid DPLL4 settings.
This patch fixes the issue by resetting the DPLL4 clock input
divider to /1 when the input clock is not 13MHz. AM/DM37x TRM
section 3.5.3.3.3.2.1 specifies that the /6.5 setting is only
used when the input clock is 13MHz.

In case of AM3517 and AM3505 (which is OMAP3 varients), IVA2 and
ISP-CAMERA modules have been removed. So add check for cpu_family before
enabling clocks for these modules, else this impacts subsequent
power consumption and system suspend/resume functionality.

AM/DM37x is another OMAP3 variant, where the GFX clock has been
boosted to 192MHz/200MHz. So fix the GFX_DIV value for this change.
HW Errata: Due to dependency of TV out clock of 54MHz, it is not
possible to configure GFX to 192MHz. So as per HW errats, the
recommended GFX clock is 200MHz (=CORE_CLK/2).

The purpose of this patch is to prepare for adding the OMAP4 architecture, which is Cortex A9
Cortex A8 and A9 both belong to the armv7 architecture, hence the name change.
The two architectures are similar enough that substantial code can be shared.
