[PATCH] SpcrFeaturePkg: Modify PCI device interrupt setting.


Tan, Ming
 

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3D3708

The ogirinal code will cause FWTS V21.08.00 testing failed.
spcr: SPCR PC-AT compatible IRQ 0xff is invalid
spcr: SPCR PCI flags compatibility bit 0 is 0, expecting 1 for PCI device

Now modify the SpcrAcpi for following:
1. Disable the support of PC-AT compatible IRQ support.
Now only support IO-APIC interrupt type.
2. Set irq to 0.
3. Set the GSI to the value read from PCI device cfg space 0x3C.
4. Set PCI Flags to 1.
