rsun3 e0ee9d9314 Clean ISA_IO/ISA_IO_16 and VGA_IO/VGA_IO_16 attribute usage in PCI bus driver/PCI host bridge drivers/LPC/VGA device drivers. 
1. Fix the incorrect definition of EFI_PCI_IO_ATTRIBUTE_VGA_IO_16 (does not conform to the UEFI spec) in PciIo.h.
2. Add missing definitions of ISA and VGA IO attributes in PCI Root Bridge IO protocol.
3. Improve the algorithm in the PCI bus driver to get PCI platform policy from PCI Platform Protocol and PCI Override Protocol.
4. Update the PCI bus driver to use the PCI platform policy to determine the supported attributes that are returned by the EFI_PCI_IO_PROTOCOL.Attributes() function. This is required by the PI spec.
5. Add a backward compatibility workaround for PCI VGA drivers in Option ROM, which typically sets VGA_IO without checking supported attributes.
6. Update the PCI host bridge driver in PcAtChipsetPkg to report VGA_IO_16 and ISA_IO_16 instead of VGA_IO/ISA_IO attributes. Modern chipsets don’t have hardware capability to control 10-bit or 16-bit decoding for ISA/VGA aliases.
7. Update LPC/VGA device drivers to check supported attributes of VGA_IO/VGA_IO_16 or ISA_IO/ISA_IO_16.

rsun3 6051620257 Update resource degrade algorithm in PCI bus driver. (1)If any child device has both option ROM and 64-bit BAR, degrade its PMEM64/MEM64 requests in case that if a legacy option ROM image can not access 64-bit resources. (2) If there are both PMEM64 and PMEM32 requests from child devices, which can not be satisfied by a P2P bridge simultaneously, keep PMEM64 and degrade PMEM32 to MEM32. (3) PMEM64/MEM64 are not supported when firmware is in 32-bit mode.
