Jiaqing Zhao 75b031b63c dm: pci: read dsm size from igd device for igd passthrough ...

Currently the DSM (Data of Stolen Memory) size was hardcoded to 64M in
ACRN, meaning that users must set "DVMT Pre-Allocated" to 64M in order
to make IGD passthrough (GVT-d) to work. This patch reads the BIOS-
configured memory size from GGC (GMCH Graphics Control, 0x50) register
and passthrough corresponding area to guest.
