Ouch. Immediately after sending this I noticed that I omitted the
cover-letter. Sorry folks.

In a nutshell - idea is to support providing some IC specific
operations at gpio_regmap registration. This should help broaden the
gpio-regmap IC coverage without the need of exposing the gpio_chip.

Some preliminary discussion can be seen here:
