AGESA f14: Fix MemContext buffer parser for AmdInitPost()
Memory training data that is saved as part of S3 feature in SPI
flash can be used to bypass training on normal boot path as well.
When RegisterSize is 3 in the register playback tables, no register is
saved or restored. Instead a function is called to do certain things in
the save and resume sequence. Previously, this was overlooked, and the
pointer containing the current OrMask was still incremented by 3 bytes.
