This series performs minor AS_CONTROL clean up.

Patch 1 to 5 rename and document AS_CONTROL config functions. There is
no functional change. All functions are now prefixed by mmu_hw_ for
consistency. All of them also expect locking. I choose not to suffix
them by _locked, but I can be convinced.

Patch 6 to 7 eliminiate redundant mmu_hw_wait_ready. This is the main
functional change of the series. panthor_vm_flush_range no longer waits
for UNLOCK to complete.

Patch 8 to 10 give mmu_hw_flush_caches final touches, to improve error
handling, simplifying code, etc.
