Add a new device tree property `v8r_el1_msa` to select the MSA (memory system architecture) at EL1 for Armv8-R architecture: MPU or MMU, the former is the default if the property is not passed. Implement the dom0less path to parse the new device tree property, add a new domctl hypercall input parameter `v8r_el1_msa` for arm and add the sanitisation in arch_sanitise_domain_config(), the parameter is intended to be used on CONFIG_MPU systems and returns an error if selected for MMU. While there, add explicit padding and check that it's zero during arch domain config sanitisation, given the breaking change, bump the XEN_DOMCTL_INTERFACE_VERSION.
