superio: Uncomment the w83627uhg UART clock source initialization

The asrock/imb-a180 mainboard is the first mainboard to use this
    w83627uhg/nct6627UD sio. The default h/w clock setting is 0. Adding
    the SIO in the mainboard Kconfig made the builder complain that the
    set_uart_clock_source() wasn't being used. So the calls to that function
    were uncommented.
