powerpc/mpc85xx/p1_p2_rdb_pc: clean up memory map 

- Sort by address, and fix column alignment

- Don't label things as localbus that aren't.  Instead, put chipselect
  info at the end of the description for localbus windows.  Note that
  NAND/NOR have their chipselects swapped when booting from NAND, and CS2
  can be either PMC or VSC7385 depending on hwconfig.

- Shrink NAND to the 32K that's actually mapped in the localbus

- Assign an address and size to L2 SRAM.  Remove the similarly named
  but unintelligible "L2 SDRAM(REV.)".

- Remove the untrue comment about L1 stack being mapped with TLB0.
