NPCX79nxB chips add UART FIFO support with 16-bytes of TX/RX buffers. This CL enables the UART FIFO mode when NPCX79nxB chips are used. The UART interrupt priority is decreased from 1 to 4 because now it has the capability to buffter data in the FIFO when ec is serving the interrupts with higher priority. BRANCH=none BUG=none TEST=No build errors for make buildall. TEST=stress test the uart port by shell command "while true; do echo 'taskinfo'>/dev/pts/19; sleep 0.1; done".
