drm/vc4: Correct generation check in vc4_hvs_lut_load
Commit 24c5ed3ddf27 ("drm/vc4: Introduce generation number enum")
incorrectly swapped a check of hvs->vc4->is_vc5 to
hvs->vc4->gen == VC4_GEN_4 in vc4_hvs_lut_load, hence breaking
loading the gamma look up table on Pi0-3.
Correct that conditional.
