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].

read/int gpio and fix properties order in example
- Remove parsing of gains from DT
- Handle vdd regulator
- Fix return value in filter_en write handler
- Link to v1: https://lore.kernel.org/r/20240703-iio-pac1921-v1-0-54c47...
