Add support for Adreno 660 to the drm/msm driver. Very similar to A650
on the kernel side.

v2:
 - added AOP PDC path for a650 and use it for a660 too
 - fix UBWC config for a650 (also affects a660)
 - add CP_PROTECT update, and corresponding a660 settings in A660 patch

v3:
 - removed patches already picked up by robclark
 - added patches for missing PC_DBG_ECO_CNTL/GMU_CX_FALNEXT_INTF settings
 - changed a660_protect to exclude CP_PERFCTR_CP_SEL
 - removed 635 id from adreno_is_a650_family
 - squashed a660 patches

SM8250 AOP firmware already sets up PDC registers for us, and it only needs
to be enabled. This path will be used for other newer GPUs.

downstream msm-5.14 kernel added a write to this register, so match that.

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.
