This allows the driver to operate as an output slave.
It adds scan out pixmap, and the capability
checks to make sure they available.

If we get asked to pci open a device with a kms path override,
make sure they match, otherwise this driver can steal the primary
device binding for a usb adaptor.
The driver should fallback to the old probe entry point in this case.

the cirrus driver presents certain challenges, and this is a
workaround, until we can possibly agree some sane interface
for exposing this information.

due to interaction between option handling and set depth, we need
to what fbdev does to get the device path early.

Currently the driver only probes a device when it has a
busID. The busID is optional so don't depend on it.

To make the driver work on nin PCI devices we shouldn't bail
out in this case.

When no devicename is found in the option then the driver probes
by PciInfo no matter if it's valid or not. Instead of doing this
use PciInfo only when it's valid and fall back to the devicename
otherwise. With devicename probing use open_hw() to fall back
on the KMSDEVICE environment variable or to the default device.

probe_hw opens the hardware in the order we want it:
first try devname, if this is NULL then try the KMSDEVICE
environment variable and as a last fallback use "/dev/dri/card0".
Instead of implementing the same code again when really opening
the device move the code to a open_hw() function and let probe_hw
use it.

in Probe() the indention shows what's meant but there are no

If the kernel rejects a cursor, cause a fallback, this isn't 100% as
we can lose the initial cursor, but it works fine once wm starts.

This isn't perfect, it should really do more with bus id matching
and finding the write drm device using sysfs if it can. but it removes
lots of hardcoding of pci ids.
