hwreset: Move reset code in dev/hwreset

We've removed kernel option EXT_RESOURCES almost two years ago.
While it was ok to have some code under a common 'extres' subdirectory
at first, we now have a lot of consumer of it and we made it mandatory
so no need to have it under a cryptic name.

arm: allwinner: Fix audio for Allwinner H3/H5

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.

Add support for Allwinner H3 audio codec.

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.

EXTRES: Add OF node as argument to all <foo>_get_by_ofw_<bar>() functions.
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.
