Unlike the the very close A740 GPU on the SM8550 SoC, the A750 GPU
doesn't have an HWCFG block but a separate register set.

The missing registers are added in the a6xx.xml.h file that would
require a subsequent sync and the non-existent hwcfg is handled
in a6xx_set_hwcg().

The A750 GPU info are added under the adreno_is_a750() macro and
the ADRENO_7XX_GEN3 family id.

This adds:
- DT nodes

Dependencies: None

Tested using Mesa's main branch on the SM8650-QRD
and with kmscube & vkcube to test basic rendering.
