vc/amd/agesa/f16kb/Proc/GNB: Fix out-of-bounds read
Incorrect values read from a different memory region will cause
incorrect computations. VceFlags array size should be 4 based on
similar code in f15 branch, and because
f16kb/Proc/GNB/Modules/GnbInitKB/GnbF1TableKB.c only loads
4 values for VceFlags in DefaultPpF1ArrayKB. Leaving it at 5
results in an out-of-bounds read of PP_FUSE_ARRAY_V2_fld16
in line 901 of
f16kb/Proc/GNB/Modules/GnbGfxIntTableV3/GfxPwrPlayTable.c
when Index reaches 4.
