Ruiyu Ni db27e9f3d8 OvmfPkg/LegacyRegion: Support legacy region manipulation of Q35 
Current implementation only supports legacy region of 440 chip.
When QEMU is launched in Q35 mode using CSM enabled OVMF image,
LegacyBios driver fails to start due to the legacy region
[0xC0000, 0xFFFFF] cannot be written.

v2:
 * just updates the comments.

v3:
 * uses PcdOvmfHostBridgePciDevId as Jordan suggested.
