mb/google/dedede/var/boten: Update LTE GPIO configuration

Browse source 
LTE module is not expected to be powered off during warm reset. Hence
configure the LTE_PWR_OFF_ODL (GPP_A10) gpio pad reset configuration to
PWROK and set the TX state to 1.

BUG=b:163100335
BRANCH=dedede
TEST=Verified through the waveforms that power sequence is meeting the LTE module requirements.
