Song Qiang 121354b2ec iio: magnetometer: Add driver support for PNI RM3100
PNI RM3100 is a high resolution, large signal immunity magnetometer,
composed of 3 single sensors and a processing chip with a MagI2C
interface.

Following functions are available:
 - Single-shot measurement from
   /sys/bus/iio/devices/iio:deviceX/in_magn_{axis}_raw
 - Triggerd buffer measurement.
 - DRDY pin for data ready trigger.
 - Both i2c and spi interface are supported.
 - Both interrupt and polling measurement is supported, depends on if
   the 'interrupts' in DT is declared.
