    This change modifies the mainbus(4) entry point for all x86 sub-archs
    in the following way:

    i) It provides a unified entry point in
       x86/x86/mainbus.c:mainbus_attach()
    ii) It carves out the preliminary bus attachment sequence that is
       common to all sub-archs into
       x86/x86/mainbus.c: x86_cpubus_attach()
    iii) It consolidates the remaining pathways as internal callee
       functions so that these may be called piecemeal if required. A
       special usecase of this is XEN PVHVM which may need to call the
       native configure path, the xen configure path, or both.
    iv) It moves the driver private data structures from
       i386/i386_mainbus.c to an x86/ level one. This allows for other
       sub-arch's to do similar, if needed. (They do not at the moment).
    v) For dom0 kernels, it enables 'acpi0 at mainbus?' and
       'acpi0 at hypervisorbus'. This serves two purposes:
       a) To demonstrate the possibility of dynamic configuration tree
          traversal ordering changes.
       b) To allow for the common acpi_check(self, "acpibus") call in
       x86/mainbus.c to not barf when it is called from the dom0 attach
       path. We allow for the acpi0 device to be a child of mainbus with
       the changes to amd64/conf/XEN3_DOM0 and i386/conf/XEN3PAE_DOM0
       without actually probing further in the code. This path will later
       be pursued in a PVHVM boot codepath.

    There should be no operative changes with this change. If there are,
    please complain loudly.
