drivers/intel/fsp1_1: Remove extra include references

Remove include references to the soc include directory which are not
required to build the FSP driver.  Remove "duplicate" include file
definitions from file that include fsp/romstage.h.  Move the definition
of fill_power_state into soc/pm.h to ensure it is still available.

TEST=Build and run on Galileo
