drm/panel: sharp-lq101r1sx01: Don't call disable at shutdown/remove
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 Tegra boards. The Tegra driver appears to
be correctly calling drm_atomic_helper_shutdown() so we can remove the
calls.
