Subject: [RFC PATCH v2 2/4] iio: adc: sun4i-gpadc-iio: rename A23/A33-specified registers to contain A23

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.

Signed-off-by: Icenowy Zheng <icenowy@...c.io>

Splited from RFC v1's 2/3.
