npcx: Adjust relative IRQ priorities for high-priority UART
Our UART interrupt must be able to preempt our SHI_CS interrupt,
otherwise console input may be lost. Adjust our relative IRQ priorities
to accommodate this.
BUG=chrome-os-partner:55920
BRANCH=None
TEST=Run `echo "kbpress 11 4 1" > /dev/pts/17` on kevin 200 times from
the recovery screen, verify that all input is received by the EC.
