From: Mahesh Kumar <mahesh1.kumar@xxxxxxxxx>
This patch passes skl_wm_level structure itself to watermark
computation function skl_compute_plane_wm function (instead
of its internal parameters). It reduces number of arguments
required to be passed.
v2: Addressed review comments by Shashank Sharma
v3: Adding reviewed by tag from Shashank Sharma
