This patch fixes a couple of bugs in the DA9121 driver.
One in an uninialised string I forgot to remove when changing to of_parse_cb()
The other is an index for an optional DT property which overflows

There is a missing "return ret;" on this error path so we call
"da9121_check_device_type(i2c, chip);" which will end up dereferencing
"chip->regmap" and lead to an Oops.

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.
