Ken Chang c93ddb60aa crossystem: read recovery switch status from chromeos_arm device ...

The kernel chromeos_arm platform device provides the recovery status
with the consideration of active polarity.
Thus make crossystem to read from chromeos_arm device first. If this
is not available, read directly from gpio pin status.

BUG=chrome-os-partner:36425
BRANCH=none
TEST=ran on kitty,
'crossystem recoverysw_cur' return 0 with recovery switch off
'crossystem recoverysw_cur' return 1 with recovery switch on
