drivers: gpio: max22190: Add MAX22190 octal input with diagnostics

Add max22190 gpio driver with input functionality, since device
support only input without output.

Implemented diagnostic funcionality for all 8 channels
which include various check to over/under voltage and wire break.
Filtering configuration is done from devicetree on per channel
bases and is configured on chip start.

In case of some fault condition occure FAULT pin drive LOW which
prop to FAULT registers to be read. Data is stored in data structure
for furter analizes and ERR message is prited in console.
