mk802-ii.fex: Disable unused soc parts

The .fex file as found in the android boot partition is a copy and paste
job from previous EVB (evaluation board) .fex files, as the name tag in
there clearly indicates. But the mk802-ii does not come with an ethernet
socket, lcd, tv-out, etc. So lets make the fex file match the actual hardware
and disable those parts of the A10-soc.

This fixes for example an unusable eth0 interface showing up in "ifconfig -a"
