drivers: gpio: Add MAX14916 industrial output

Industrial 8 channel output with advanced diagnostics. Allowing giagnostic configuration both on per channel or global bases In SPI communication diagnostic status transmitted on every READ/WRITE which includes generic status of chip. Diagnostics includes : * Oveload * Open Wire * Over current * Short to VDD * Thermal Shutdown * VDD Warn * Watch Dog Error * Communication Error * VDD under voltage Add app.overlay for MAX14916 driver. Tested with adopted basic/blinky example. Signed-off-by: Stoyan Bogdanov <[email protected]>
