[PATCH] staging: drm/omap: move where DMM driver is registered

[Rob Clark]

From: Rob Clark <rob at ti.com>

Not sure what triggered the change in behavior, but seems to
result in recursively acquiring a mutex and hanging on boot.  But
omap_drm_init() seems a much more sane place to register the
driver for the DMM sub-device.
