* bus enumeration fixups are not PCIBIOS-specific, interrupt fixups are done
by both PCIBIOS and ACPI. The redundancy is very redundant. Therefore,
rename PCIBIOS_*_FIXUP to PCI_*_FIXUP, use PCI_INTR_FIXUP in place of
ACPI_PCI_FIXUP, and change code refences to match.
* move the fixup defines from opt_pcibios.h to opt_pcifixup.h to reflect
the above.
* fix up the PCI bus numbering in mainbus_attach(), right after we detect the
configuration mode. This probably renders the fixup in pcibios.c
redundant -- but it should be harmless.
These changes make cardbus work in ACPI-only machines, when PCI_BUS_FIXUP
and PCI_INTR_FIXUP are defined.
attimer(4) is the new body of the part of pcppi(4) that mapped the TIMER1
register to set the pitch of the bell. It was necessary to separate them
in order to have a working ACPI attachment (as the two appear as different
devices in the ACPI structures).

While here, remove a printf() in mpu_attach() (ic/mpu.c) to remove
an empty line in some frontends (mpu_isa.c, etc).
which bustype should be attached with a specific call to config_found()
(from a "mainbus" or a bus bridge).
Do it for isa/eisa/mca and pci/agp for now. These buses all attach to
an mi interface attribute "isabus", "eisabus" etc., and the autoconf
framework now allows to specify an interface attribute on config_found()
and config_search(), which limits the search of matching config data
to these which attach to that specific attribute.
So we basically have to call config_found_ia(..., "foobus", ...) where
such a bus is attached.
As a consequence, where a "mainbus" or alike also attaches other
devices (eg CPUs) which do not attach to a specific attribute yet,
we need at least pass an attribute name (different from "foobus") so
that the foo bus is not found at these places. This made some minor
changes necessary which are not obviously related to the mentioned buses.
Note: the default behavior is changed. Now we don't disable the ACPI
subsystem on power off (halt -p) by default.
'options ACPI_DISABLE_ON_POWEROFF' in a kernel config file makes the kernel
behave the way we used to be.
