x86: fsp: Rename update_fsp_upd() and change its signature

To support platform-specific configurations (might not always be
UPD on some platform), use a better name update_fsp_configs() and
accepct struct fsp_config_data as its parameter so that platform
codes can handle whatever configuration data for that FSP.
