Nicolas Boichat 51b6222520 npcx/uart: Pull up communication line during transaction
Boards needs to define GPIO_EC_COMM_PU, which needs to be driven
high during EC-EC transaction. This makes sure that the line does
not go low, even when the base goes away during the transaction.

BRANCH=none
BUG=b:68954760
TEST=EC-EC communication works with this change.
TEST=With signal analyzer, check that UART line is always kept
     high while transaction is in progress.
