1. why get_gpu_time_panthor exists? it's just a copy of get_gpu_time get_gpu_time_panfrost exists because it needs two values to calculate usage, but it's not the case with panthor
2. i think it's better to rename get_gpu_clock_panfrost to get_gpu_clock_mali and add mali_gpu_clock_fdinfo_key variable in gpu_fdinfo.h and make get_gpu_clock_mali use it to avoid duplicate code

otherwise everything good
