[PATCH] Staging: dt3155: remove useless dt3155_major parameter

[H Hartley Sweeten <hartleys@visionengravers.com>]

The dt3155_major variable was never exposed as a parameter so just make it
static and always allocate a dynamic major when registering the driver.

Also, remove a couple unnecessary comments and printk noise associated with
the major/minor numbers and registration.
