We want to remove per minor debugfs directories. Start by stopping
drivers from adding anything inside of those in the mid layer callback.

v2: drop it for the accel node as well

I tested with accel and ivpu driver.

I believe main concern of prevent access before registering
is already solved. Any plans to apply this ?
