Subject: [PATCH v3 15/30] iio: adc: sun4i-gpadc-iio: rename A33-specified registers to contain A33

From: Icenowy Zheng <icenowy@...c.io>

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.
