[PATCH v3 3/3] drm/drv: fix module_init() usage

[Koen Koning <koen.koning@linux.intel.com>]

Use subsys_initcall() instead of module_init() (which compiles to
device_initcall() for built-ins) for drm_drv, so its initialization code
always runs before any (built-in) drivers.
This happened to work correctly so far due to the order of linking in
the Makefiles, but this should not be relied upon.
