All boards in tree use 0. Looks like this is all work that was
never completed and tested.
We also have static setting sysconf.segbit=0 which would conflict
with PCI_BUS_SEGN_BITS>0.
Having PCI_BUS_SEGN_BITS>0 would also require PCI MMCONF support
to cover over 255 buses.

This reverts the revert commit 5780d6f387
and fixes the build issue that cuased it to be reverted.
Verstage will host vboot2 for firmware verification.
It's a stage in the sense that it has its own set of toolchains,
compiler flags,
and includes. This allows us to easily add object files as needed. But
it's directly linked to bootblock. This allows us to avoid code
duplication for stage loading and jumping (e.g. cbfs driver) for the
boards
where bootblock has to run in a different architecture (e.g. Tegra124).
To avoid name space conflict, verstage symbols are prefixed with
verstage_.

Because we had no stack on romcc boards, we had a separate, not as
powerful clone of printk: print_*.
Back in the day, like more than half a decade ago, we migrated a lot
of boards to printk, but we never cleaned up the existing code to be
consistent. Instead, we worked around the problem with a very messy
console.h (nowadays the mess is hidden in romstage_console.c and
early_print.h)
This patch cleans up the generic code pieces to use printk() on all
non-ROMCC boards.
Our two remaining ROMCC boards are fixed up in this commit:
bifferos/bifferboard and dmp/vortex86ex.
