Subject[PATCH 0/2] ARM: dra7: fix DCAN glitch

If "default" pins are active for CAN then there is a slight
window during boot when CAN pins are in active mode and can
affect DRA7 CAN stability. This is because device core
automatically selects "default" before probe.

These patches change "default" pins to inactive and adds
a new "active" pin state so that we don't encounter
the glitch mentioned above.
