Subject: iio: accel: sca3300: Accelerometer support and binding docs

Hi,
Patch series adds driver and dt-bindings for Murata SCA3300 accelerometer.

Device is a 3-axis Accelerometer with digital SPI interface.

Patches are tested and based on linux-next.

Changes V2:
- Add manufacturer name to dt-binding file
- Update spdx license statement for dt-bindings
- Remove murata,opmode devicetree property in favor of driver scale + frequency properties
- Add copyright year for driver
- Remove X_READ and X_WRITE defines
- Add _available sysfs attributes
- Fix errors in documentation formatting
- Use ARRAY_SIZE where applicable
- Use get/put_unaligned_be16() helpers where applicable
- Factor out error handling to separate function
- Return only negative values from transfer function
- Fix INFO_SCALE to return multiplier instead of inverted value
- Change INFO_SCALE values to be actual scale instead of mode value
- Do not provide INFO_PROCESSED values for user space
- Add error message for failed data read in irq handler
- Move trigger handler timestamping as part of pushing data to buffers
- Document startup sequence, providing reference to data sheet section
- Convert iio_triggered_buffer_setup to devm_iio_triggered_buffer_setup,
making remove() obsolete
