Maíra Canal 6a0ee2a61a mfd: wcd934x: Replace legacy gpio interface for gpiod
Considering the current transition of the GPIO subsystem, remove all
dependencies of the legacy GPIO interface (linux/gpio.h and linux
/of_gpio.h) and replace it with the descriptor-based GPIO approach.

Srinivas Kandagatla a7618119c2 mfd: wcd934x: Add macro for adding new interrupts
Currently only two interrupts supported is added in wcd934x interrupt controller,
however if we are adding more interrupts the file will become too much unreadable.

So add a macro to make adding new interrupts easy and also convert existing
slim and soundwire interrupts to use it.
This is in preparation to enable Multi Button Headset Control support on this
codec.

WCD934x supports Multi Button Headset control which enable headset detection
along with headset button detection.

This patch adds interrupts required for MBHC functionality.

It's not necessary to free memory allocated with devm_kzalloc
and using kfree leads to a double free.
