Subject: [PATCH v3 0/5] i2c: xiic: use generic device property accessors

Switch to generic device property accessors and make minor code
refactoring.

Make the clock optional since the driver is designed to operate without
explicit configuration in firmware thus making it useful on platforms
where clock is not or cannot be provided.

Changed in v2:

* Split the patch into two independent changes.
* Added struct device *dev at the top of probe() and remove() to re-use.
* Switched to device_set_node(...)

Changes in v3:
- Reorder the "optional clock" patch to be the first in the series. 
- Add a patch to switch to devm_mutex_init().
- Remove dup message in error path.
- Cosmetic: use temporary dev variable.
- Link to v2: https://lore.kernel.org/r/20260122-i2c-xiic-v2-0-134f5d743e8b@nexthop.ai
