Oliver Smith-Denny 909abd7104 EmbeddedPkg: NonCoherentDmaLib: Set EFI_MEMORY_XP Capability on DMA Buffer ...

Commit 8984fba2f22a2cd44e1189403e3553f447b82852 added setting the
EFI_MEMORY_XP attribute on DMA buffers. However, it did not ensure
that the XP capability was set on that region.

This patch adds setting the XP capability before attempting to set
the attribute. If setting the capability fails, it defaults to the
old behavior of not setting the XP bit.
