zinger: fix reading of output and discharge gpio states

Browse Source 
Change the reads of output enable and discharge gpio's to use
the output data register (ODR) instead of reading input data
register (IDR) because we are really intending to read it's output
state, what we have set it to.

BUG=none
BRANCH=zinger
TEST=make -j buildall. load on zinger and use it normally.
