drm/msm/dpu: don't use active in atomic_check()

Browse source

[ Upstream commit 25b4614843 ]

The driver isn't supposed to consult crtc_state->active/active_check for
resource allocation. Instead all resources should be allocated if
crtc_state->enabled is set. Stop consulting active / active_changed in
order to determine whether the hardware resources should be
(re)allocated.
