[PATCH] split plymouth module

[Dave Young <dyoung-H+wXaHxf7aLQT0dZR+AlfA@public.gmane.org>]

Kdump module will need the drm and kms kernel modules so user can see the
emergency shell at least.

Fix this by split 50plymouth module to 50drm and 50plymouth. Moving the
installkernel part to 50drm so user can use drm directly without adding
extra plymouth utils.
