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 gpu id of this gpu to communicate to the userspace driver.

Changes in v2: - Introduce adreno_is_a660_family() (Rob) - Remove revn for 7c3 (Rob) - Remove CPR register programing since they are not required for 7c3
