Add iam20380 sensor support.
- add binding doc
- Add support for the Invensense IAM20380 sensor to the MPU6050 driver. It is
similar to the IAM20680. But IAM20380 only supports gyro and WHOAMI
register data is difference
Signed-off-by: Frank Li <Frank.Li@nxp.com>

Changes in v2:
- Add Conor Dooley's ack tag for binding doc
- use iio_chan_spec
- Add spi part
- Link to v1: https://lore.kernel.org/r/20241113-iam20380-v1-0-cae690c4674d@nxp.com

Add compatible string "invensense,iam20380" for the Invensense IAM20380
sensor. The IAM20380 is similar to the IAM20680, but only supports gyro.

Hello,
overall looks good, but I've got one concern.
The gyro bits used for scan mask are the same than other chips, meaning bits 4, 5, 6, and timestamp is bit 7, and these are the only bits since the chip is gyro only. Usually scan mask bits start at 0. I don't know if starting from 4 will work or not.
Jonathan,
do you know if this can be an issue?
Thanks,
JB
