saa7134: get rid of KBL

From: Mauro Carvalho Chehab <mchehab@redhat.com>

KBL is not needed on saa7134, so, let's remove it.

However, we should take some care to avoid opening the module while
initializing it. This issue exists with newer udev's that opens a device
as soon as the driver is registered. So, a proper lock is needed on
open.
