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.

As noted by Harald Welte, HWFLOW support in the S3C64XX serial driver is
broken and currently unused. Remove it.

Notice: USB on S3C6400 currently works _only_ with switched off MMU. One could
try to enable the MMU, but map addresses 1-to-1, and disable data cache, then
it should work too and we could still profit from instruction cache.

DM644x is just one of a series of DaVinci chips that use the EMAC driver.
By replacing all the function names that start with dm644x_* to davinci_*
we make these function more portable. I have tested this change on my EVM.
DM6467 is another DaVinci SOC which uses the EMAC driver and i will
be sending patches that add DaVinci DM6467 support to the list soon.
