soc/intel/quark: Enable HSUART1
Enable HSUART1 for debug serial output. Specify the fixed resources in
the UART driver. This keeps debug serial output flowing during the rest
of the device initialization.
Testing on Galileo:
* Edit the src/mainboard/intel/galileo/Makefile.inc file
* Add "select ADD_FSP_PDAT_FILE"
* Add "select ADD_FSP_RAW_BIN"
* Add "select ADD_RMU_FILE"
* Place the FSP.bin file in the location specified by CONFIG_FSP_FILE
* Place the pdat.bin files in the location specified by
CONFIG_FSP_PDAT_FILE
* Place the rmu.bin file in the location specified by CONFIG_RMU_FILE
* Testing successful if:
* Debug serial output stays enabled after BS_DEV_RESOURCES state
