V4L/DVB (12492): saa7134-input: don't probe for the Pinnacle remotes anymore

With the recent improvements we don't need to probe anymore, if we know
the i2c address of the receiver.

The address of the receiver for the remote with the gray buttons is not
confirmed anywhere, but it is very unlikely to see it on something else.

We want to have that information anyway.

BTW, those remaining still probing, please join.
