gblues 1d84c0eca1 Fix analog for DS3, plus some cleanups
== DETAILS

- DS3 analog wasn't working mainly because I forgot to actually declare the
  axes in input/input_autoconfig.c when declaring the pad. Whoops.
- I also moved the axis decoding logic to a more central place, because it
  clearly is not Wii U specific.
- Removed some dead commented-out code

== TESTING

Can use analog inputs on both GCA and DS3. Tested in Mario 3 on Nestopia core.

Haven't tested with any actual analog games, but I did confirm via logging
that the correct ranges are produced.
