W86224 haptic driver

Hi,

This series enables the haptics of the Motorola Edge 30.

The first patch adds the binding documentation for the AW86224, which is compatible with the AW86927 haptic driver.

The second one contains the driver. The AW86224 differs from the AW86927 in many respects, so writing a new driver seemed the simpler approach.

The third one enables it in the sm7325-motorola-dubai-common DTS.

I removed Enrico from the v2 recipient list because his email address is not working.

Sashiko found a bug in the 3rd patch, which was fixed in v3.

2.56.0

Add the AW86224 haptic device to the binding documentation for the AW86927 and AW86938, as this binding needs the same properties.

They are not compatible though, because the chip identification works differently compared to the 86927/86938

Changes in v3:
- none

Changes in v2:
- add only the new element (Krzysztof)

Add support for the I2C-connected Awinic AW86224 LRA haptic driver.

The chip supports multiple modes of which only RAM mode is implemented.
