soc/intel/skylake: Initialize LPSS UART based on DRIVERS_UART_8250MEM_32

pch_uart_init and base address assignment should be done
    based on DRIVERS_UART_8250MEM_32 config selection. Enabling
    legacy UART for debug on RVP does not require additional UART2
    programming.

TEST=Build and boot SKL RVP to have serial log through legacy UART.
