soc/intel/broadwell: Rename `ramstage.h`

This file only contains the `broadwell_run_reference_code()` function
prototype (either a declaration or an inline stub definition). Rename
this file to refcode.h and only include it where necessary.

Tested with BUILD_TIMELESS=1, Purism Librem 13 v1 remains identical.
