[PATCH v5 0/3] iio: imu: inv_icm42600: add support for icm42630

The TDK InvenSense ICM-42630 is a 6-axis IMU of the ICM-42600 family,
used in the Fairphone 6. It needs no part-specific driver code: TDK
confirmed it can be supported by inv_icm42600 without modification.

The binding documents the new compatible with an invensense,icm42631
fallback, and a WHOAMI mismatch no longer fails probe, so that a
fallback-matched part can probe; one informational line records the
mismatch, and a whoami of 0x00/0xff (no response) still fails. No
driver id entries are added: the part binds through the fallback.

Tested on the Fairphone 6 with the fallback pair in the devicetree,
via a backport to its 7.1-based kernel: matched as icm42631 through
the fallback, the part probes with the one informational line, and
accelerometer, gyroscope and temperature reads work.

Changes in v5:
- patch 2: the no-response guard moves before the whoami-mismatch
  comparison as its own check (Andy); it does not depend on
  hw->whoami, since no supported part uses either value
- patch 2: the four Link trailers are dropped (Andy, Jonathan); the
  Suggested-by tags carry the attribution
