[PATCH v5 0/4] drm/imagination: Clean up MIPS firmware interfaces

[Alexandru Dadu <alexandru.dadu@imgtec.com>]

1. Limits access to the MIPS firmware interface, keeping its state
   within the relevant implementation.
2. Align MIPS firmware headers with the other processor headers and add
   "_fw_" component to the headers filename.
3. Improved logging in error paths.
4. Simplify MIPS PTE definitions.
