The skylake-based Chromebooks use a separate verstage which runs
just after bootblock and prior to romstage. The normal path for
romstage would be to reload the gdt, however in the previously
described scenario has verstage performing that work. Therefore,
provide that path under those conditions. The only difference
from the C_ENVIRONMENT_BOOTBLOCK scenario is that the stack
should not be reloaded since there's no way to know the top
of the stack.

The path that just clears CAR_GLOBAL variables and jumps
to the stage entry point needs another condition for
separate verstage just after bootblock. However, the
current conditional is a negative conditional so
swap the logic around to make it easier to extend.

for the coreboot infrastructure that are architecture
