Subject: [PATCH] soc/intel/quark: FSP MemoryInit Support

Add a dummy fill_power_state routine so that execution is able to reach
FSP MemoryInit.

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"
   *  Add "select DISPLAY_HOBS"
   *  Add "select DISPLAY_UPD_DATA"
*  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:
   *  MemoryInit returns 0 (success) and
   *  The the message "ERROR - Coreboot's requirements not met by FSP
binary!" is not displayed
