drm/panfrost: Consolidate reset handling
Runtime PM resume and job timeouts both call the same sequence of
functions, so consolidate them to a common function. This will make
changing the reset related code easier. The MMU also needs some
re-initialization on reset, so rework its call. In the process, we
hide the address space details within the MMU code in preparation to
support multiple address spaces.
