This series is an attempt at cleaning up the regmap-irq API in order
to simplify things and consolidate existing features, while at the
same time generalizing it to support a wider range of hardware.

There is a new system for IRQ type configuration, some tweaks to
unmask registers so they're more intuitive and useful, and a new
callback for calculating register addresses. There's also a few
minor code cleanups in here.

Several existing features have been marked deprecated. Warnings will
be issued for any drivers that use deprecated features, but they'll
otherwise continue to function normally.

One important caveat: not all of these changes are tested beyond
compile testing, since I don't have hardware to exercise all of
the features.

v3 changelog

* Fix bug in patch 11/12 reported by Marek Szyprowski

v2 changelog

* Drop driver patches, these will be sent as separate series to the
  appropriate subsystem maintainers.
* Drop patches that remove deprecated features, that should be done
  in a separate series.
* Various fixups to address Andy Shevchenko's v1 review comments.
* Drop patches that changed the behavior of mask_writeonly; instead
  just remove the flag.
