drivers/intel/fsp2_0: Handle FspNotify calls

Other SOC platforms need to handle the FspNotify calls in the same way
as Apollo Lake.  Migrate the FspNotify calls into the FSP 2.0 driver.
Provide a platform callback to handle anything else that needs to be
done after the FspNotify call.

Display the MTRRs before the first call to fsp_notify.

TEST=Build and run on Galileo Gen2
