drivers: adc: add LMP90xxx ADC driver with GPIO

Browse source 
Add driver for the Texas Instruments LMP90xxx series of multi-channel,
low-power 16-/24-bit sensor analog frontends (AFEs).

The functionality is split into two drivers; an ADC driver and a GPIO
driver.

Tested with LMP90080 and LMP90100.
