[RFC 2/4] drm: Register drmfs filesystem from drm init

[swati.dhin...@intel.com]

From: Sourab Gupta <sourab.gu...@intel.com>

The drmfs filesystem will not be registered standalone during kernel init time,
instead it is intended to be initialized/registered during drm initialization.
This again is dependent on CONFIG_DRMFS being defined.
