soc/intel/quark: Enable Serial Port
Add the code to enable debug serial output using HSUART1:
* Enable the code using Kconfig value ENABLE_BUILTIN_HSUART1
* Note that the BIST value is always zero as validated in
esram_init.inc
* The initial TSC value is currently not saved!
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 is successful if serial output is present on HSUART1 at
115200 baud, 8-bit, no parity
