iio: adc: qcom-spmi-adc5-gen3: Add support for qcom,debug-base

Browse Source 
Currently, the debug base address is defined under the reg property. This
would be confusing if multiple addresses are specified under reg property
to support more ADC channels. Separate debug base into its own property.
