PATCH v2 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

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

Any comments on this patch? I found a few minor bugs, so I have a v3 waiting, but I want to address any other comments before I post another patch. If no one has any comments, I'll just go ahead and post my v3 now.
