drm/amd/display: add DC drm_panic support

Browse source

Add support for the drm_panic module, which displays a pretty user
friendly message on the screen when a Linux kernel panic occurs.

It doesn't work yet on laptop panels, maybe due to PSR.

Adapted from Jocelyn's original patch to add DC drm_panic
support.
