Add support for the Freescale P1022DS. Driver support is limited to:
 - I2C
 - Ethernet
 - Serial
 - NOR flash
 - PIXIS FPGA

System clock configuration is read from the FPGA but has only been
tested using a 133MHz system clock and 100MHz DDR clock.

Boot arguments are defined in the environment to boot over NFS with
a console configured at 115200 bauds.

Enabling branch prediction is moved from board support to the platform
support for all boards as it is a CPU feature.

Some the code is from U-Boot version git-be937b5.

The chip select 0 (boot flash) registers are updated by the board
specific code as it is not done by the cpu early initialisation
any more.

The FSF address has changed in the past. Instead of updating it
each time the address changes, just drop it completely treewide.

This is limited board support for the Freescale P2020RDB in single CPU
mode. The DDR is configured for a memory bus running at 667Mhz.
The system boots from NOR flash and provides the console at 115200
bauds, no other drivers are included.

Finally, the PPC Kconfig and make file make the building of
the P2020RDB platform firmware possible.
