From: "Edgar E. Iglesias" <edgar.igles...@xilinx.com>
Since the hardware domain is a trusted domain, we extend the
trust to include making final decisions on what attributes to
use when mapping memory regions.
For device-tree configured hardware domains, this patch relaxes
the hardware domains mapping attributes to p2m_mmio_direct_c.
This will allow the hardware domain to control the attributes
via its S1 mappings.
