freedreno: Sync registers with envytools

Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/5557>

freedreno: Include adreno_pm4.xml.h before adreno_a6xx.xml.h

This matches the XML, and soon adreno_a6xx.xml will start including
types from adreno_pm4.xml.

gallium/swr: Fix compilation warnings

In some places in SWR cod objects are initialized using
memset/memcpy. This is usually done to enable
allocating those objects in aligned memory.
It generates compilation warnings though,
which are worked around by casting the pointers to void*
before calling memset/memcpy.

pan/decode: Make mapped memory read-only while decoding

This will help catch any bugs where descriptors are accidentally
modified.

v2: Use a dynarray of ro memory mappings rather than iterating through
    the mmap hash table.
