  1. drivers: gpio: Add MAX14906 industrial input/output 

    MAX14906 in 4 channel I/O with advanced diagnostic.
In SPI communication diagnostic status transmitted on every
READ/WRITE which includes generic status of chip.
Configuration both on global level and on per channel bases.
Diagnostics includes :
 * Thermal overload
 * current limit
 * open wire detection
 * short to VDD
 * Above VDD
 * Safe DEmagnitization fault
 * VDD warning
 * VDD low
 * SPI/CRC Error
 * WDog Error
 * Loss GND

Add app.overlay for MAX14906 driver.

Tested with adopted basic/button and basic/blinky sample.
