[PATCH 1/6] resource: mark normal memory as supporting being uncacheable

[Ahmad Fatoum]

The attributes report what the underlying memory is capable of,
so if we can configure it as WT/WC/WB, it's likely we can configure it
as uncached as well. This doesn't hold true for all architectures, but
it does for ARM, so add it to the MEMATTRS_NORMAL bitfield for now.
