vc/amd/agesa/f.../Proc/Mem/Tech/DDR3: Support a custom memory profile
The ability to set up a custom memory profile is useful if you don't
like the XMP memory profiles (if they exist) of your RAM sticks, or
want to try some overclocking. Read SPD data will be overriden by your
custom values. Tested on Crucial BLT8G3D1869DT1TX0 (1866MHz 9-9-9-27).
