OvmfPkg ResetSystemLib: Fix shutdown via UEFI runtime services
When the PM base address was moved from 0x400 to 0xb000, this code was missed. This prevented shutdown's via the UEFI system call from working. (For example, at the EFI shell prompt: reset -s) We now use gUefiOvmfPkgTokenSpaceGuid.PcdAcpiPmBaseAddress which is currently set at 0xb000.
