3.2.61-rc1 review patch. If anyone has any objections, please let me know.

commit 2fc68eb122c7ea6cd5be1fe7d6650c0beb2f4f40 upstream.
Support for firmware rev 508+ was added years ago, but we never noticed it reports channel in a different way for G-PHY devices. Instead of offset from 2400 MHz it simply passes channel id (AKA hw_value).
So far it was (most probably) affecting monitor mode users only, but the following recent commit made it noticeable for quite everybody:
