[PATCH V5 07/16] drm/amd/pm: create a new holder for those APIs used only by legacy ASICs(si/kv)

Mon Dec 13 03:52:14 UTC 2021
Those APIs are used only by legacy ASICs(si/kv). They cannot be
shared by other ASICs. So, we create a new holder for them.

Change-Id: I555dfa37e783a267b1d3b3a7db5c87fcc3f1556f
--
v1->v2:
- rename amdgpu_pm_compute_clocks as amdgpu_dpm_compute_clocks(Lijo)
v2->v3:
- add back the lock protections dropped unintentionally(Lijo)
