PATCH v3 1/1 powerpc: add support for the Freescale P1022DS reference board

Add basic suport for the Freescale P1022DS reference board.

Specifics:

1) 36-bit only
2) Booting from NOR flash only
3) Environment stored in NOR flash only
4) No SPI support
5) No DIU support

This patch is for the 'next' branch.

v3: Fixed minor issues, ported to new makefile format

v2: addresses most of Wolfgang's concerns.
DIU support removed so that it can be reworked later

This depends on the following patches:

Move ICS CLK chip frequenty calculation code into a common board library
fsl: add LAW target to fsl_pci_info structure

Sure, can you update against 85xx upstream tree. Some Makefile changes will break this patch.

It applies against Wolfgang's 'next' branch. Have you updated your branch to pull in the new Makefile code?
