Naming these components has been quite a challenge for our upstreaming
effort. Some things are not very obvious unless you know he chip or
were involved in those discussions.

"Kona" can be thought of as an architecture or a family of chips.
bcm281xx is one member of that family. There are others. I submitted
bcm21664 to arm-linux just a few minutes ago. bcm21664 also uses
gpio-bcm-kona.c.

Mentioning the SoCs in the help text is a good idea, but we'll likely
have to come up with a central location where all supported members of
the Kona family are listed, so they aren't scattered all over
different sub-systems (Kona watchdog, Kona GPIO, Kona timer, etc.) If
we don't have a central location, we'll be certain to forget updating
one of the help texts eventually, and it would become inconsistent.
