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}. BUG=chrome-os-partner:44827 BRANCH=None TEST=Built and booted glados.
