driver/intel/fsp1_1: Fix boot failure for non-verstage case
Currently car_stage_entry is defined only in romstage_after_verstage and
as a result when SEPARATE_VERSTAGE is not selected, there is no
entry point into romstage and romstage will not be started at all.
The solution is move out romstage_after_verstage.S from fsp1.1 driver
to skylake/romstage. And add CONFIG_PLATFORM_USES_FSP1_1 to fix the
build and boot issue with this change.
Besides that, rename the romstage_after_verstage to romstage_c_entry
in more appropriate naming convention after this fix.
Tested on SkyLake Saddle Brook (FSP 1.1) and KabyLake Rvp11 (FSP 2.0),
romstage can be started successfully.
