[PATCH v13 07/16] sparc/PCI: Add IORESOURCE_MEM_64 for 64-bit resource in OF parsing

[Yinghai Lu <yinghai@kernel.org>]

For device resource with PREF bit setting under bridge 64-bit pref resource,
we need to make sure only set PREF for 64bit resource.

so this patch set IORESOUCE_MEM_64 for 64bit resource during OF device resource
flags parsing.
