AMD Bettong: add memory configuration for DDR3 and DDR4
1. Bettong Rev A-E are DDR3, Bettong Rev F is DDR4.
Rev F's SPD address is different from DDR3.
0 1
Channel A A0 A2
Channel B A4 AC
2. DDR4 uses different memory configuration in AGESA.
Pass memory configuration parameters in agesawrapper_amdinitpost.
3. Tested on Rev C and Rev F.
Both of them can boot to Windows 8 and have the correct memory size.
