Replace the avr32-specific board_init_info hook by the standard
board_early_init_r hook and make it optional.
board_early_init_r() runs somewhat earlier than board_init_info used to
do, but this isn't a problem for any of the in-tree boards.

Replace the avr32-specific gclk_init() board hook with the standard
board_postclk_init() hook which is supposed to run at the same point
during initialization.
Provide a dummy weak alias for boards not implementing this hook. The
cost of this is:
- 2 bytes for the dummy function (retal 0)
- 2 bytes for each unnecessary function call (short rcall)
which is a pretty small price to pay for avoiding lots of #ifdef
clutter. In this particular case, all boards probably end up slightly
smaller because we avoid the conditional checking if the gclk_init
symbol is NULL.

Add two helper functions for configuring and enabling generic clocks:
- gclk_enable_output: Enables output on a GCLKx pin
- gclk_set_rate: Configures a gclk to run at a specific rate
This should eliminate any reason to go mucking about with PM registers
from board code.

- Separate the portmux configuration functionality from the GPIO pin
control API.
- Separate the controller-specific code from the chip-specific code.
- Allow "ganged" port configuration (multiple pins at once).
- Add more flexibility to the "canned" peripheral select functions:
- Allow using more than 23 address bits, more chip selects, as
well as NAND- and CF-specific pins.
- Make the MACB SPEED pin optional, and choose between MII/RMII
using a parameter instead of an #ifdef.
- Make it possible to use other MMC slots than slot 0, and support
different MMC/SDCard data bus widths.
- Use more reasonable pull-up defaults; floating pins may consume a
lot of power.
- Get rid of some custom portmux code from the mimc200 board code. The
old gpio/portmux API couldn't really handle its requirements, but
the new one can.
- Add documentation.
The end result is slightly smaller code for all boards. Which isn't
really the point, but at least it isn't any larger.
This has been verified on ATSTK1002 and ATNGW100. I'd appreciate if
the board maintainers could help me test this on their boards. In
particular, the mimc200 port has lost a lot of code, so I'm hoping Mark
can help me out.

Changes since v1:
* Enable pullup on NWAIT
* Add missing include to portmux-pio.h
* Rename CONFIG_PIO2 -> CONFIG_PORTMUX_PIO to match docs

Make the data_bits enum in struct sdram_config reflect the actual number
of data bits on the bus, i.e. 16 or 32. Having 0 mean 16 bits and 1 mean
32 bits is just too confusing.

SMDK6400 can only boot U-Boot from NAND-flash. This patch adds a nand_spl
driver for it too. The board can also boot from the NOR flash, but due to
hardware limitations it can only address 64KiB on it, which is not enough
for U-Boot. Based on the original sources by Samsung for U-Boot 1.1.6.

MPC5121 rev 2 silicon has a new register for controlling how long
CS is asserted after deassertion of ALE in multiplexed mode.
The default is to assert CS together with ALE. The alternative
is to assert CS (ALEN+1)*LPC_CLK clocks after deassertion of ALE.
The default is wrong for the NOR flash and CPLD on the ADS5121.
This patch turns on the alternative for CS0 (NOR) and CS2 (CPLD)
it does so conditionally based on silicon rev 2.0 or greater.
