Add iio driver and DT binding for the Microchip PAC1921 Current/Power
monitor.

Implemented most of the features with few limitations listed in the
driver commit message.

Tested with a Pine64 host board connected to a PAC1921 click board [1]
via I2C. The PAC1921 click board embeds the Microchip PAC1921 device
and a 10 mOhms shunt resistor. The PAC1921 datasheet is at [2].

Marius, could you take a look at this driver/binding?
