google/kahlee: Add defines in OemCustomize.c 

Add a #define for MB_DIMM_SLOTS and verify it doesn't exceed the max
supported for the device.  AGESA's DRAM procedures follow the BKDG and
may vary depending on the number of slots on the motherboard.  DIMM
numbering and ordering is also affected by this value.

Replace hardcoded integers with defined values for DIMM slots and
number of channels.
