If we use the gem fb helper as the prepare_fb hook, plus the
drm_prime.c import helpers now automatically setting obj->resv, we can
use the shared helpers to wait for fences instead of rolling our own.
Note that this relies on mtk setting drm_fb->obj, which is already
done in mtk_drm_framebuffer_init().
Aside: Probably can use the default commit_tail with this again, but I
didn't check for that.

The commit 3aeeb13d89 ("drm/modes: Support modes names on the command
line") added name support to the DRM modes, and added that name to the
debug message.
However, that code tests for whether or not the name variable is NULL and
only prints it if it's not. Except that that variable is an array, so it
will never be NULL.
The original intent was to print it only when the name has been specified.
Just printing the array directly will achieve the same thing since the
drm_cmdline_mode structure that holds it is itself contained in
drm_connector, that is allocated with its whole content zero'd.
That means that if the name is not declared, the array will be all zeros,
which will not print anything.
