[PATCH RFT 0/3] Add UW Camera Actuator support for Nothing Phone (1)

This series is marked as RFT because, in addition to adding DW9800W
support, it introduces chip ID validation for DW9800K. I do not have the
DW9800K datasheet or hardware, so I cannot confirm its chip ID value.
DW9800W support, however, has been fully tested.

A separate compatible is added for DW9800W because its datasheet
specifies a different default VCM frequency than DW9800K. The register
layout is identical, but it is unclear whether DW9800K uses the same
chip ID as DW9800W.

- Patch 1 documents the new DW9800W compatible.
- Patch 2 adds DW9800W support and moves DW9800K into the chip ID
validation switch.
- Patch 3 adds the DW9800W actuator node to the sm7325-nothing-spacewar
device-tree with the vendor-provided vcm-prescale value. The vendor-
provided sac-mode value matches the driver's default and is therefore
omitted.
