sensors: Add Bosch BMA4xx-series driver

This is a driver targetting the Bosch BMA 4-series accelerometers. It
has been specifically developed for the BMA422 but should be compatible
with others in that line, excepting the BMA400. Supports key attributes
and async RTIO one-shot operation. I2C operation is supported, with
stubs for a SPI implementation provided for future improvement.
