drm/amdkfd: use correct method to get clock under SRIOV
[What]
Current SRIOV still using adev->clock.default_XX which gets from
atomfirmware. But these fields are abandoned in atomfirmware long ago.
Which may cause function to return a 0 value.
[How]
We don't need to check whether SR-IOV. For SR-IOV one-vf-mode,
pm is enabled and VF is able to read dpm clock
from pmfw, so we can use dpm clock interface directly. For
multi-VF mode, VF pm is disabled, so driver can just react as pm
disabled. One-vf-mode is introduced from GFX9 so it shall not have
any backward compatibility issue.
