dt-bindings:iio:adc:qcom,spmi-iadc: txt to yaml format conversion.

Straight forward conversion.  Not heard from Ivan in a while so if the
email bounces, I'll change the maintainer to myself for this binding unless
anyone else comes forwards.

-Qualcomm's SPMI PMIC current ADC
-
-QPNP PMIC current ADC (IADC) provides interface to clients to read current.
-A 16 bit ADC is used for current measurements. IADC can measure the current
-through an external resistor (channel 1) or internal (built-in) resistor
-(channel 0). When using an external resistor it is to be described by

-IADC node:

-    Definition: Should contain "qcom,spmi-iadc".
