Since commit d0494d9b8097 ("drm_hwcomposer: Fixes for display hotplug /
headless mode"), which introduced an extra call to de-active the display
on de-init, we've seen regressions on db845c with the
VtsHalGraphicsComposerV2_3TargetTest test set.
This seems to be due to an issue on db845c, where after putting the
lt9611 bridge to sleep, the connection detection stops working even
after the chip is reset.
However, on changing the kernel driver to avoid putting the bridge
to sleep so connect detection works, we start to see SIGSEGV crashes
in drm_hwcomposer.
So this patch is a workaround to restore previous behavior to avoid
the regression until we can sort out a proper fixes to db845c and
drm_hwcomposer.
