drm/msm/dpu: move _dpu_plane_get_qos_lut to dpu_hw_util file



_dpu_plane_get_qos_lut() is not specific to just dpu_plane.
It can take any fill level and return the LUT matching it.
This can be used even for other modules like dpu_writeback.

Move _dpu_plane_get_qos_lut() to the common dpu_hw_util file
and rename it to _dpu_hw_get_qos_lut().
