mainboard/intel/cannonlake_rvp: Set LPSS UART2 to hidden
If LPSS UART port had been set up to hidden mode, FSP will not force
8 bit transition mode (AKA 16550 compatible UART mode).
BRANCH=none
TEST=Boot up coreboot and check LPSS UART debug printing after silicon
init. If mismatch, the print will became much slower.
