ppc4xx: Update AMCC Acadia support for board revision 1.1
This patch updates the Acadia (405EZ) support for the new 1.1 board
revision. It also adds support for NAND FLASH via the 4xx NDFC.
Please note that the jumper J7 must be in position 2-3 for this
NAND support. Position 1-2 is for NAND booting only. NAND booting
support will follow later.
