    xen/arm: dt: Relax hw domain mapping attributes to p2m_mmio_direct_c
    
    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.
