This patch adds the clock output pin functions on the A20.
The 2 pins can output a configurable clock to be used by
external modules. This is used on the CubieTruck, to supply
a 32768 Hz low power clock to the onboard Wifi+BT module.

The Allwinner A20 is pin-compatible with the older A10, so the two pin
set are quite similar. However, since the A20 has new features, we can't
just use the A10 pin set as is, and we need to define our own for the
A20.

The Allwinner A31 SoC uses the same IP than the one found in the
A10/A13, with only different pins. Add the pins and the associated
functions found in the A31.

Some pin functions in the array were not indented like the other
functions in this array. Fix this.

It will allow us to have a cleaner separation between the data needed by
the driver to work, and the core logic of the driver in itself, and will
allow having too much noise in the core driver in the future.
