drm/panel: synaptics-r63353: Fix regulator unbalance

Browse Source 
BugLink: https://bugs.launchpad.net/bugs/2102266

[ Upstream commit d2bd3fcb825725a59c8880070b1206b1710922bd ]

The shutdown function can be called when the display is already
unprepared. For example during reboot this trigger a kernel
backlog. Calling the drm_panel_unprepare, allow us to avoid
to trigger the kernel warning.
