amd/agesa/f16kb: Allow SATA Gen3 

YangtzeSataResetService implements the SataSetMaxGen2 double.
The value should be only set, if the condition is met.
For testing, add
FchParams_env->Sata.SataMode.SataSetMaxGen2 = FALSE;
to your BiosCallOuts.c, which enables GEN3 for the SATA ports.
Patch is tested with bap/e20xx board, Lubuntu 16.04 Kernel 4.4.
