OvmfPkg/PciHostBridgeLib: silence IA32 VS2015x86 warnings 

When compiling "OvmfPkg\Library\PciHostBridgeLib\XenSupport.c" for IA32,
the VS2015x86 compiler emits the following:

> XenSupport.c(41): error C2220: warning treated as error - no 'object'

PciLib functions take UINTN addresses that were encoded with the
PCI_LIB_ADDRESS() macro. We carry addresses from the macro invocations to
the function calls in two UINT64 variables however. This loses no data,
but it alerts VS2015x86. Change the variable types to UINTN.
