[RFT PATCH v2 47/48] drm/panel: sony-acx565akm: Don't call disable at remove

[Douglas Anderson]

It's the responsibility of a correctly written DRM modeset driver to
call drm_atomic_helper_shutdown() at shutdown time and that should be
disabling / unpreparing the panel if needed. Panel drivers shouldn't
be calling these functions themselves.

A recent effort was made to fix as many DRM modeset drivers as
possible [1] [2] [3] and most drivers are fixed now.

A grep through mainline for compatible strings used by this driver
indicates that it is used by TI OMAP boards. The TI OMAP driver
appears to be correctly calling drm_atomic_helper_shutdown() so we can
remove the calls.
