OvmfPkg/SmmControl2Dxe: correct PCI_CONFIG_READ_WRITE in S3 boot script
EFI_BOOT_SCRIPT_PCI_CONFIG_READ_WRITE_OPCODE expects the PCI address to
access in UEFI encoding, not in edk2/PciLib encoding.
Introduce the POWER_MGMT_REGISTER_Q35_EFI_PCI_ADDRESS() macro, and with
it, store the ICH9_GEN_PMCON_1 register's address to the boot script in
UEFI representation.
