drm/panthor: Add support for Mali-G1 GPUs

Browse Source 
Add support for Mali-G1 GPUs (CSF architecture v14), introducing a new
panthor_hw_arch_v14 entry with reset and L2 power management operations
via the PWR_CONTROL block.

Mali-G1 introduces a dedicated PWR_CONTROL block for managing resets and
power domains. panthor_gpu_info_init() is updated to use this block for
L2, tiler, and shader domain present register reads.
