feat(tc): enable gpu/dpu scmi power domain and also gpu perf domain

Browse source 
The scmi-perf-domain property is a custom property while we
wait for proper support in the kernel for using the scmi_pm_domain
driver and scmi_perf_domain driver at the same time.

GPU operating points are now in the SCP firmware.
