Revert "Disable ipv6 again... still causes issues with gps"

This reverts commit 0ac1680223b5d2c7aa5a0a0bc62ae0b09714c300.
Remove recovery command from board.  Requires kernel patches.
We now use bootmode injection on the kernel side, no need for this.
This also fixes issues of random reboots into recovery when using
certains apps to reboot.
