vendorcode/amd/agesa: Fix variable length array declaration
Definition of S_PSTATE only allowed PStateStruct[0], while it is
effectively used as a flexible array. Since sizeof(S_PSTATE) is
reduced here by sizeof(S_PSTATE_VALUES), we have to account for
that when calculating PStateLevelingSizeOfBytes.
In S_PSTATE context, PStateStruct[PStateMaxValue] is valid reference.
GCC 7.2.0 warns about an out of bounds array subscript.
```
