Log Message:
Introduce sys/arch/x86/x86/mp.c for common x86 MP configuration code.
mpacpi_scan_pci() and mpbios_scan_pci() are identical code, so replace
them with mp_pci_scan().

Introduce mp_pci_childdetached(), which helps us to detach root PCI
buses that were enumerated either by MP BIOS or by ACPI.

Let us detach and re-attach PCI buses from mainbus0 on i386.  This is
necessarily a work-in-progress, because testing detach and re-attach
is very difficult: to detach and re-attach the entire PCI tree on most
x86 computers that I own is not possible because some essential device
attaches under the PCI subtree: the console, com0, NIC, or storage
controller always attaches in the PCI tree.
