2021-06-09sb/intel/lynxpoint: Add SerialIO UART console supportAngel Pons
Derived from Broadwell and adapted to follow what soc/intel does. Note that SERIALIO_UART_CONSOLE is meant to be selected from the mainboards which expose a SerialIO UART. UART_FOR_CONSOLE also needs to be set in mainboard Kconfig accordingly. It is possible that some of the UART configuration steps in bootblock are unnecessary. However, some of the steps turn off power management features and others are undocumented: omitting them could cause weird issues. Finally, add a config file to ensure the code gets build-tested. Tested on out-of-tree Compal LA-A992P, SerialIO UART 0 can be used to receive coreboot and SeaBIOS logs.
