[PATCH v5 18/19] drm/msm/dpu: relax parameter validation in encoders

[Jeykumar Sankaran <jsanka-sgV2jX0FEOL9JmXXK+q4OQ@public.gmane.org>]

DPU, being over protective, validates every parameter of a
module. This change traces the call stack for some of encoder
functions affected by previous set of clean up patches and
cleans up unwanted validations.
