Make the facility for recognizing BIOS-signatures more general
and return a printable representation.

This fixes recognition of the PC Engines WRAP and improves the
recognition of the Soekris boards (Bios version can now be
seen in the dmesg output for instance).

Also, add watchdog support for PCM-582x platforms.

Remove atdevbase and replace it's remaining uses with direct references to
KERNBASE instead.

Add new bios_string() which will hunt for a string inside a given range
of the BIOS. This can be used for finding arbitrary magic in the BIOS
in order to recognize particular platforms.

use __packed.

Fix the argument specifier for the PnP BIOS function 2
(PNP_SET_DEVNODE). The second argument is not a segment:offset
pointer, but a 16 bit short.

The general conesnsus on irc was that pci bios for config registers
and such was just a bad idea and one that users should be forced to
enable if they want it. This patch introduces a hw.pci.enable_pcibios
tunable for those people. This does not impact the pcibios interrupt
routing at all.

More updates to the ACPI code:

- Move all register I/O into acpi_io.c
- Move event handling into acpi_event.c
- Reorganise headers into acpivar/acpireg/acpiio
- Move find-RSDT and find-ACPI-owne

- Reorganise headers into acpivar/acpireg/acpiio
- Move find-RSDT and find-ACPI-owned-memory into acpi_machdep
- Allocate all resources (except those detailed only by AML)
as real resources. Add infrastructure that will make adding
resource support to AML code easy.
- Remove all ACPI #ifdefs in non-ACPI code
- Removed unnecessary includes
- Minor style and commenting fixes

Reference the correct gdt[] entry on SMP. Remove the `generation' flag,
and always reload the selectors for every bios call.

Remove the SMBIOS detection and definitions; this should be handled in a
loadable module (under development).

A simple rewrite of biossmap.c:

- Do not iterate int 15h, function e820h twice. Instead, we use STAILQ to
store each return buffer and copy all at once.
- Export optional extended attributes defined in ACPI 3.0 as separate
metadata. Currently, there are only two bits defined in the specification.
For example, if the descriptor has extended attributes and it is not
enabled, it has to be ignored by OS. We may implement it in the kernel
later if it is necessary and proven correct in reality.
- Check return buffer size strictly as suggested in ACPI 3.0.
