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.
