[Arm-netbook] a10 cpu has SPDIF

[lkcl luke]

hmmm...  still haven't picked which of the 16 GPIOs should go out on
the EOMA68 connector.  i'm inclined to put 12 of them to be group G -
PG0 to PG11.

for non-EOMA-compliant situations, that would give access to either
camera-in (CSI), one of the TS groups, SDC1 and two UARTs (3 and 4).

that would leave 4 pins... i'm inclined towards one of the PWMs and
the 3 GPS pins.

thoughts?
