Add OFW PCI subroutines if PCI support is included in the kernel.

Driver for the I2C bus used for RAM serial presence detection. This
I2C interface is implemented by bit-banging a couple of GPIO pins on
the Sequoia core logic used in the Shark.

Heavy lifting by Julian Coleman, and minor tweaks and a different
autoconfiguration scheme by me.

- Introduce sequoiaLock() / sequoiaUnlock() functions that hide away
the details of what's going on (disable / restore interrupts), and
use it consistently.
- Give "sequoia" a device_t in the system device tree, matching on
the Shark's /vlbus/isa node, acting a subclass of ofisa (an "ofisa"
will be attached to "sequoia"). This allows us to attach other logical
device nodes to the "sequoia".

Garbage-collect the old Shark-specific "pccons" stuff. Shark has
been wscons for some time now.

Generalise FDT and OFW

include files.usb, vlpci needs-flag

Add initial basic driver for DNARD's VT82C505 VL to PCI bridge.

Currently only allows configuration space, and I/O space access, the
latter of which has not yet been tested. DMA support is currently
unimplemented.

Add commented lines to GENERIC.

Since files.wscons et al. are included by ~all ports anyway, include
them in the mi "files" file, and remove include statements from md files.
These shouldn't pull in additional kernel code when not in use, so it
shouldn't do any harm except a risk of namespace collisions which
should be easy to fix.

Interrupt handling changes, in discussion since February:

- Reduce available SPL levels for hardware devices to none, vm, sched, high.
- Acquire kernel_lock only for interrupts at IPL_VM.

Merge the gehenna-devsw branch into the trunk.

This merge changes the device switch tables from static array to
dynamically generated by config(8).

- All device switches is defined as a constant structure in device drivers.

- The new grammer ``device-major'' is introduced to ``files''.

device-major <prefix> char <num> [block <num>] [<rules>]

- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.

- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.

- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.
