All architectures enable NEW_PCIB in DEFAULTS (arm being the most recent
to do so in 121be55599 (arm: Set NEW_PCIB in DEFAULTS rather than a
subset of kernel configs")), so it's time we removed the legacy code
that no longer sees much testing and has a significant maintenance
burden.

Also, pccbb isa attachment is never going to happen, do disconnect it from the
build (will delete this in future commit). It would need to be updated as well,
but since this code is effectively dead code, remove it from the build instead.
would be picked up for kernel builds, it isn't picked up for
old-fashioned builds. Without this option, PCI bus numbers are busted
for modules build iteratively.
This means that the kernel can be totally self contained now and is not
dependent on the last buildworld to update /usr/share/mk. This might
also make it easier to build 5.x kernels on 4.0 boxes etc, assuming
gensetdefs and config(8) are updated.
