ADDR_BIT_SWIZZLE (addr_bit_swizzle):
Each bit is set in case of the corresponding 2-rank UDIMM or certain 
LRDIMM requires address mirroring/swizzling. It indicates that some of the 
address bits are swizzled for rank 1 (or rank 3), and this has to be 
considered in MRS command. The address swizzling bits:
A3 and A4
A5 and A6
A7 and A8
BA0 and BA1
Bit 24 refers to DIMM 0
Bit 25 refers to DIMM 1
Bit 26 refers to DIMM 2
