Due to three conditions the codec driver for Allwinner A10/A20 and H3/H5 did not work properly here:
Wrong bit position for the analog audio reset
Hardware Reset of codec was not de-asserted correctly
Linux DTS file did not contain the address of the analog register the way as the driver was expecting it.
This patch proposes fixes for those three parts.

The audio controller in the H3 is more or less the same as A10/A20 except
some registers are shuffled around. The mixer interface, however, is
completely different between SoCs. Separate a10_mixer_class and
h3_mixer_class implementations are now made available. This will also make
adding support for other SoCs easier in the future.

In some cases, the driver must handle given properties located in
specific OF subnode. Instead of creating duplicate set of function, add
'node' as argument to existing functions, defaulting it to device OF node.
