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 A33, in order to
prevent obfuscation with H3 registers. Currently these registers are
only prefixed "SUN8I", not "SUN8I_A33".

Add "_A33" after "SUN8I" on the register names.

Changes in v4:
- Change A23 to A33, as the driver never supports A23.
