soc/intel/apollolake: Enable decoding for ComA and ComB on LPC
If there is an external 8250 UART, one needs to enable the appropriate
address ranges before console_init() is called so that the init sequence
can reach the external UART.
Furthermore FSPM needs different settings for an external UART port. For
this, the function fill_console_params() has to be adapted.
