From: Mahesh Kumar <[e-mail]>

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

v4: Added reviewed by from Juha-Pekka Heikkila

v5: Rebased the series
