fsp_broadwell_de: Enable Super I/O address range decode

Hardware / Coreboot - Werner Zeh [siemens.com] - 30 June 2016 03:54 UTC

If there is an external 16550 like UART, one needs to enable the appropriate address ranges before console_init() is called so that the init sequence can reach the external UART. Otherwise the UART will only start working in ramstage and will produce unreadable characters in romstage due to the lack of initialization.

Tested-on: Siemens MC_BDX1
