AMD/Bettong: Memory configuration for DDR3 and DDR4 

1. Bettong Rev A-E are DDR3, Bettong Rev F is DDR4.

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.
