msm: mdss: fix pgc lut read failure in thulium
config payload in pgc(programmable gamma correction) was assigned
to wrong structure type. When driver client requests for reading
pgc lut(look up table) driver sanity checks fail due to incorrect
type assignment. This change fixes the pgc lut read failure.
