northbridge/amd/amdfam10: Redirect legacy VGA memory access to MMIO
Commit 27baa32 (cpu/amd/model_10xxx: Do not initialize SMM memory if
SMM is disabled) deactivated TSeg SMRAM, which had the side effect
of routing legacy VGA memory access to DRAM. Restore the correct
MMIO mapping via the MMIO configuration registers.
TEST: Booted KGPE-D16 with nVidia 7300LE card and verified proper VGA
functionality.
