arch/x86: provide verstage support for CONFIG_C_ENVIRONMENT_BOOTBLOCK
When CONFIG_C_ENVIRONMENT_BOOTBLOCK is employed there's no need for
a chipset specific verstage entry point because cache-as-ram has
already been initialized. Therefore, provide a default entry point
for verstage in that environment.
