The goal here is to keep things consistent. Nothing in this driver as it currently is mentions A23. Unless you plan on adding additional commits to support the A23, and a note explaining the similarity of the A23 and A33 ADCs, this is only going to confuse people.

As the H3 SoC, which is also in sun8i line, has totally different register map for the thermal sensor (a cut down version of GPADC), we should rename A23/A33-specified registers to contain A23, in order to prevent obfuscation with H3 registers. Currently these registers are only prefixed "SUN8I", not "SUN8I_A23". Add "_A23" after "SUN8I" on the register names.
