This is a really awkward interface, since we're calling it well before
the driver knows what device it's going to drive. Drivers with both KMS
and UMS support therefore don't know whether to say they need I/O port
access or not, and have to assume they do.
With this change we now call it only to query whether port access might
be needed; we don't use that to determine whether to call a driver's
probe function or not, instead we call them unconditionally. If the
driver doesn't check whether port access was enabled, they might crash
ungracefully. To accomodate this, we move xorgHWAccess to be explicitly
intentionally exported (sigh xf86Priv.h) so that drivers can check that
before they attempt port access.
v2: Move initial xf86EnableIO() nearer the logic that determines whether
to call it, suggested by Simon Farnsworth.

This solves a race if we are trying to dynamically power off
secondary GPUs. Its not the greatest fix ever but it probably
as good as we can do for now.
The GPU probing causes the devices to be powered up, then when
we scan the PCI bus we get the correct information from the kernel,
rather than a bunch of 0xff due to the device being powered off.

On Linux in order for future hotplug work, we are required to interface
to udev to detect device creation/removal. In order to try and get
some earlier testing on this, this patch adds the ability to use
udev for device enumeration on Linux.
At startup the list of drm/kms devices is probed and this info is
used to load drivers.
A new driver probing method is introduced that passes the udev
device info to the driver for probing.
The probing integrates with the pci probing code and will fallback
to the pci probe and old school probe functions in turn.
The flags parameter to the probe function will be used later
to provide hotplug and gpu screen flags for the driver to behave
in a different way.
This patch changes the driver ABI, all drivers should at least
be set with a NULL udev probe function after this commit.
v2: rename to platform bus, now with 100% less udev specific,
this version passes config_odev_attribs around which are an array
of id/string pairs, then the udev code can attach the set of attribs
it understands, the OS specific code can attach its attrib, and then
the core/drivers can lookup the required attribs.
