[PATCH] of/PCI: Add IORESOURCE_MEM_64 for 64-bit resource

[Yinghai Lu <yinghai@kernel.org>]

For device resource PREF bit setting under bridge 64-bit pref resource,
we need to make sure only set PREF for 64bit resource, so set IORESOUCE_MEM_64
for 64bit resource during of device resource flags parsing.
