drm/amd/pm: Remove wm_low and wm_high fields from amdgpu_crtc (v2)

Browse Source 
These fields were only used by si_dpm and are not necessary
anymore. They also may have been incorrect because:
- wm_high was set to the LOW_WATERMARK field of watermark A.
- wm_low was not set on DCE 6 and was always zero.
