drivers/intel/fsp1_1: fix linking romstage when SEPARATE_VERSTAGE used
The skylake-based Chromebooks use a separate verstage which runs
just after bootblock and prior to romstage. However, that
config is not enabled for coreboot.org so when
C_ENVIRONMENT_BOOTBLOCK changes were done it wasn't observed
that the Chromebook config failed because 2 _start symbols
were present. Remedy this failure by using the common
car_stage_entry symbol for taking over control flow.
