Adds interrupt handler for variants, and notifications for events; over
temperature/voltage/current. Because the IRQs are triggered by persisting
status, they must be masked and the status polled until clear, before the
IRQ can be enabled again.

Update bindings for the Dialog Semiconductor DA9121 voltage regulator to
add device variants.
Because several variants have multiple regulators, and to regard potential
to add GPIO support in future, the 'regulators' sub-node is added,
following the precedent set by other multi-regulator devices, including
the DA9211 family. This breaks compatibility with the original submission
by Vincent Whitchurch - but as this is still in for-next, the alignment
could be made before upstreaming occurs.

Add NXP PF8100/PF8121A/PF8200 regulator driver.
PF8100/PF8121A/PF8200 is PMIC designed for highperformance
consumer applications. It features seven high efficiency buck,
four linear and one vsnvs regulators.
Tested in Engicam i.Core MX8M Mini SOM platform boards.
