[PATCH v3 09/20] xen/dom0less: abstract Arm-specific p2m type name for device MMIO mappings

[Oleksii Kurochko <oleksii.kurochko@xxxxxxxxx>]

Rename `p2m_mmio_direct_dev` to a more architecture-neutral alias
`p2m_mmio_direct` to avoid leaking Arm-specific naming into common Xen code,
such as dom0less passthrough property handling.

This helps reduce platform-specific terminology in shared logic and
improves clarity for future non-Arm ports (e.g. RISC-V or PowerPC).

No functional changes — the definition is preserved via a macro alias
for Arm.
