Add Maxim max34408/34409 ADC driver and yaml for it. Until now it
supports only current monitioring function without overcurrent
threshold/delay, shutdown delay configuration, alert interrupt.
Changes from v1:
- minor changes from Rob's comments for yaml
- add ena, shtdn and make 4 inputs for R sense from Jonathan's comments for yaml
- add _REG suffix and make prefix for bitmasks and statuses
- add SCALE/OFFSET instead of AVG/PROCESSED from Jonathan and
Lars-Peter comments
- add chip data from Jonathan and Lars-Peter comments
- minor changes from Lars-Peter and Jonathan comments for driver
Changes from v2:
- add channels into hardware description into yaml
- add rsense property per channel
- rename pins for shtdn and ena pins
- make one array for input_rsense values
Changes from v3:
- change *_34408_OCT3 and 4 to *_34409_OCT3 and 4
- change of_property_read_u32 to fwnode family calls
- add i2c dev table
- change of_match_device to i2c_of_match_device
- change match->data to i2c_get_match_data
