Subject: [PATCH v2 1/2] iio: imu: lsm6dsx: Support SMOCF05 ACPI ID for LSM6DS3TR-C

Same device (LSM6DS3TR-C), different integration with the firmware.

The integration differs in that the firmware provides the SLA0 and SLG0
mounting matrices. They are assumed to be Accelerometer and Gyroscope.

Observations were made against the Windows driver, version
`12/06/2023,1.0.4.3`. This driver supports both identifiers, but expose
the device in different ways.
