drm/panthor: Fix firmware initialization on systems with a page size > 4k
The system and GPU MMU page size might differ, which becomes a
problem for FW sections that need to be mapped at explicit addresses
since our PAGE_SIZE alignment might cover a VA range that's
expected to be used for another section.
Make sure we never map more than we need.
Changes in v3:
- Add R-bs
Changes in v2:
- Plan for per-VM page sizes so the MCU VM and user VM can
have different pages sizes
