[PATCH V4 00/10] Add Invensense ICM42607

[Chris Morgan <macroalpha82@gmail.com>]

From: Chris Morgan <macromorgan@hotmail.com>

Add support for the ICM42607 IMU. This sensor shares the same
functionality but a different register layout with the existing
ICM42600.

This driver should work with the ICM42607 and ICM42607P over both I2C
and SPI, however only the ICM42607P over I2C could be tested.

Changes Since V1:
 - Instead of creating a new driver, merged with the existing inv_icm42600
   driver. This necessitated adding some code to the existing driver to
   permit using a different register layout for the same functionality.
 - Split changes up a bit more to decrease the size of the individual
   patches. Note that patch 0004 is still pretty hefty; if I need to split
   further I may need to create some temporary stub functions.
 - Used guard() and PM_RUNTIME_ACQUIRE_AUTOSUSPEND() on the new functions
   per Jonathan's recommendations.

Changes Since V2:
 - Went back to using a new driver on advice from Invensense engineer.
 - Further split changes up into smaller chunks of functionality. Note
   still that the largest patch is approximately 900 lines, and that while
   the driver compiles cleanly at each commit it is not able to drive the
   hardware until the commit that adds the Interrupt (as it also adds the
   Makefile).
 - Change the error to a warning when the devicetree binding does not match
   the hardware ID.
 - Dropped the ack on the devicetree bindings, as I am creating a new file
   (for a new driver) instead of modifying the existing one.

Changes Since V3:
 - Numerous small fixes (too many to list here). Thank you to everyone who
   provided feedback.
 - Split power management additions into an additional commit to break
   things up further.
 - Consolidated devicetree documentation in existing
   invensense,icm42600.yaml file.
 - Removed most of the FIELD_PREP from header file to c files to make code
   easier to read.
 - Changed scale values to 2D arrays for Gyro and Accelerometer.
 - Removed IIO_CHAN_INFO_CALIBBIAS attribute.
