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.
