The current design has the following problem:
uos kernel may update gvt bars' regions,
but ACRN-DM doesn't know this update.
ACRN-DM only know out-of-date gvt bar regions,
For simplicity, mark these bar regions as OOD bar regions.
uos kernel may allocate OOD bar regions for
other pci devices, which will result in ACRN-DM
bar regions inconsistency with uos kernel.
The new design is the following:
When other pci device update bar regions
(1) ACRN-DM updates gvt bars' regions
provided by a system file.
(2) ACRN-DM updates this pci device bar regions
v5 -> v6:
* add more comments
v4 -> v5:
* remove & for callback func assignment
v3 -> v4:
* compare gpu bar address to avoid unnecessary
* unregistered/registered operation
