vc/amd/agesa/f.../Proc/Mem/Tech/DDR3: Support XMP memory profiles

Add XMP memory profiles support that has been tested on f15tn (A88XM-E)
and f16kb (AM1I-A) with two Crucial BLT8G3D1869DT1TX0, XMP 1 profile.
Added using the datasheets from https://github.com/mikebdp2/ddr3spd :
JEDEC_DDR3_SPD_4_01_02_11R24.pdf and Intel_XMP_Spec_Rev1.1.pdf
