drm/msm/a6xx: Add A740 support

A740 builds upon the A730 IP, shuffling some values and registers
around. More differences will appear when things like BCL are
implemented.

adreno_is_a740_family is added in preparation for more A7xx GPUs,
the logic checks will be valid resulting in smaller diffs.

drm/msm/a6xx: Add support for Adreno 7c Gen 3 gpu

This patch adds support for the gpu found in the Snapdragon 7c Gen 3
compute platform. This gpu is similar to the exisiting a660 gpu with
minor delta in the programing sequence. As the Adreno GPUs are moving
away from a numeric chipid based naming scheme to a string, it was
decided to use 0x06030500 as the chip id of this gpu to communicate
to the userspace driver.

drm/msm/a6xx: add support for Adreno 660 GPU

Add adreno_is_{a660,a650_family} helpers and convert update existing
adreno_is_a650 usage based on downstream driver's logic (changing into
adreno_is_a650_family or adding adreno_is_a660).

And add the remaining changes required for A660, again based on
the downstream driver: missing GMU allocations, additional register init,
dummy hfi BW table, cp protect list, entry in gpulist table, hwcg table,
updated a6xx_ucode_check_version check.

drm/msm/a6xx: add build_bw_table for A640/A650

This sets up bw tables for A640/A650 similar to A618/A630, 0 DDR bandwidth
vote, and the CNOC vote. A640 has the same CNOC addresses as A630 and was
working, but this is required for A650 to work.

Eventually the bw table should be filled by querying the interconnect
driver for each BW in the dts, but use these dummy tables for now.

drm/msm/a6xx: Poll for HFI responses

The only HFI communication with the GMU on sdm845 happens
during initialization and all commands are synchronous. A fancy
interrupt tasklet and associated infrastructure is entirely
not eeded and puts us at the mercy of the scheduler.

Instead poll for the message signal and handle the response
immediately and go on our way.

drm/msm: Add A6XX device support

Add support for the A6XX family of Adreno GPUs. The biggest addition
is the GMU (Graphics Management Unit) which takes over most of the
power management of the GPU itself but in a ironic twist of fate
needs a goodly amount of management itself. Add support for the
A6XX core code, the GMU and the HFI (hardware firmware interface)
queue that the CPU uses to communicate with the GMU.
