NEW_PCIB and arm take 3 (4?)

[John Baldwin]

The plan for NEW_PCIB was for it to be a temporary option that would 
eventually become the default on all platforms.  I have long had patches to 
provide the one step of infrastructure (namely implementing "real" 
bus_activate_resource methods) for various arm chipsets, but I haven't been 
able to get anyone to review or test them.  I'm about at the point of just 
committing them in a week barring any specific reports from testers or 
reviewers.

You can read more about what NEW_PCIB is at:

   https://wiki.freebsd.org/NEW_PCIB

These patches aim to implement step 2 from that wiki page.  However, I have no 
way to test them (and to be honest, I haven't recently tested to see if they 
will compile.  I will ensure make universe passes before pushing them in if it 
comes down to that.)

As I noted previously, I don't know how to properly fix i80321_pci in large 
part because I do not understand what it is doing.  Warner had previously 
suggested just dropping it and if the consensus is to do that, I'd be much 
obliged for someone to make it so.
