intel fsp1_1: prepare for romstage vboot verification split

In order to introduce a verstage which performs vboot
verification the cache-as-ram environment needs to be
generalized and split into pieces that can be utilized
in romstage and/or verstage. Therefore, the romstage
pieces were removed from the cache-as-ram specific pieces
that are generic:

- Add fsp/car.h to house the declarations for functions in
  the cache-as-ram environment
- Only have cache_as_ram_params which are isolated form the
  cache-as-ram environment aside from FSP_INFO_HEADER.
- Hardware requirements for console initialization is done
  in the cache-as-ram specific files.
- Provide after_raminit.S which can be included from a
  romstage separated from cache-as-ram as well as one that
  is tightly coupled to the cache-as-ram environment.
- Update the fallout from the API changes in
  soc/intel/{braswell,common,skylake}.
