soc/intel/cannonlake: Add proper support to enable UART2 in 16550 mode
Need to perform a dummy read in order to activate LPSS UART's
16550 8-bit compatibility mode.
TEST=Able to get serial log in both 32 bit and 8 bit mode through
LPSS UART2 based on CONFIG_DRIVERS_UART_8250MEM_32 and
CONFIG_DRIVERS_UART_8250MEM selection.
