Thanks to all reviewers for the feedback on v1. I believe I've made all
the suggested changes, and I've also added support for the battery power
supply in this version.

Changes in v2:

* Do a little cleanup of axp20x_adc suggested by Jonathan Cameron
* Consolidate ADC read functions in axp20x_adc
* Drop the axp192's read_label callback in axp20x_adc
* Clean up the axp192-gpio dt bindings
* Rewrite a problematic bit of code in axp20x_usb_power reported
by kernel test robot
* Support AXP192 in axp20x_battery
* Split up regmap-irq changes to two separate patches

Cover letter from v1:

Hi all,

This patch series adds support for the X-Powers AXP192 PMIC to the
AXP20x driver framework.

The first patch is a small change to regmap-irq to support the AXP192's
unusual IRQ register layout. It isn't possible to include all of the
IRQ registers in one regmap-irq chip without this.

The rest of the changes are pretty straightforward, I think the only
notable parts are the axp20x_adc driver where there seems to be some
opportunities for code reuse (the axp192 is nearly a duplicate of the
axp20x) and the addition of a new pinctrl driver for the axp192, since
the axp20x pinctrl driver was not very easy to adapt.
