Add inputs to sun4i-codec:
- FM-in Left and Right
- Line-in Left and Right
- Mic1-in
- Mic2-in

Hi,
this is the sixth version of the patch that adds inputs to sun4i-codec.
Changes compared to v5 are:
- Mic preamplifier special cases for A20 and A10 now are now not icky:
There are two different _widget arrays and the probe() function now selects
the right one to pass to snd_soc_register_codec() unmodified.
- sun7i-specific things (A20-specific things) are now grouped together.
I successfully tested it again on an A20 board using alsamixer, headphones,
a radio and my ears.
Note that because of missing capturing support I tested only the mixing,
for Mic, Line, and FM.
The patches are on top of
<git://git.kernel.org/pub/scm/linux/kernel/git/mripard/linux.git>,
branch "sunxi/for-next".
Regards,
Danny
