[00/14] A7xx support

  This series attempts to introduce Adreno 700 support (with A730 and A740
found on SM8450 and SM8550 respectively), reusing much of the existing
A6xx code. This submission largely lays the groundwork for expansion and
more or less gives us feature parity (on the kernel side, that is) with
existing A6xx parts.

On top of introducing a very messy set of three (!) separate and
obfuscated deivce identifiers for each 7xx part, this generation
introduces very sophisticated hardware multi-threading and (on some SKUs)
hardware ray-tracing (not supported yet).

After this series, a long-overdue cleanup of drm/msm/adreno is planned
in preparation for adding more features and removing some hardcoding.

The last patch is a hack that may or may not be necessary depending
on your board's humour.. eh.. :/

Developed atop (and hence depends on) [1]

The corresponding devicetree patches are initially available at [2] and
will be posted after this series gets merged. To test it, you'll also need
firmware that you need to obtain from your board (there's none with a
redistributable license, sorry..). Most likely it will be in one of
these directories on your stock android installation:

* /vendor/firmware
* /vendor/firmware_mnt
* /system

..but some vendors make it hard and you have to do some grepping ;)

Requires [3] to work on the userspace side. You'll almost cerainly want
to test it alongside Zink with a lot of debug flags (early impl), like:

TU_DEBUG=sysmem,nolrz,flushall,noubwc MESA_LOADER_DRIVER_OVERRIDE=zink kmscube
