As discussed in [1] it is more convenient to use a generic `channel` node name for ADC channels while storing a friendly - board-specific instead of PMIC-specific - name in the label, if/when desired to overwrite the channel description already contained (but previously unused) in the driver [2]. Follow up on the dt-bindings' `channel` node name requirement, and instead provide this (sometimes per-board) channel description through a label property. Also remove all the unused label references (not to be confused with label properties) from pm660, pmp8074 and pms405.
