Instead of using the standard name ("gpios"), use "interrupts".

Per MFD subsystem requirements, split the IRQ part of the
driver into a separate one with just the IRQ handling code
and the powerkey support.

There are lots of fields at struct hi6421_spmi_pmic that aren't
used. In a matter of fact, only regmap is needed.
So, drop the struct as a hole, and set just the regmap as
the drvdata.
While here, add a missing dot at the Huawei's copyrights.
