Victor Sun 67ec1b7708 HV: expose port 0x64 read for SOS VM
The port 0x64 is the status register of i8042 keyboard controller. When
i8042 is defined as ACPI PnP device in BIOS, enforce returning 0xff in
read handler would cause infinite loop when booting SOS VM, so expose
the physical port read in this case;

In current architecutre, the maximum vCPUs number per VM could not
exceed the pCPUs number. Given the MAX_PCPU_NUM macro is provided
in board configurations, so remove the MAX_VCPUS_PER_VM from Kconfig
and add a macro of MAX_VCPUS_PER_VM to reference MAX_PCPU_NUM directly.

Li Fei1 5f5ba1d647 hv: vmsi: refine write_vmsi_cfg implementation
1. disable physical MSI before writing the virtual MSI CFG space
2. do the remap_vmsi if the guest wants to enable MSI or update MSI address or data
3. disable INTx and enable MSI after step 2.

The previous Message Control check depends on the guest write MSI Message Control
Register at the offset of Message Control Register. However, the guest could access
this register at the offset of MSI Capability ID register. This patch remove this
constraint. Also, The previous implementation didn't really disable MSI when guest
wanted to disable MSI.

Junming Liu 89908bf510 dm:gvt:update gvt bars before other pci devices write bar address
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ACRN-DM only know out-of-date gvt bar regions,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

v2 -> v3:
	* call unregister_bar and register_bar when update gvt bars
	* update gvt reserved regions when update gvt bars
