drm/amd/powerplay: support sysfs to set socclk, fclk, dcefclk

Browse source

Add sys interface to set socclk, fclk and dcefclk for smu.
Add feature_mask parameter for smu_upload_dpm_level as socclk, fclk and
dcefclk have dependency, without feature_mask to point out specific clk
will make it fail to set some clk.
Fix the function of smu_unforce_dpm_levels.
