Restore the correct value when disabling probes. Otherwise the instrumented
tracepoints would continue to generate traps, which would be ignored but
could consume noticeable amounts of CPU if, say, all functions in the kernel
were instrumented.

If the VM was reset via "/sbin/reboot" or "shutdown -r",
then it is no longer necessary to "bhyvectl --destroy" the VM when it reboots.
Move the "bhyvectl --destroy" outside of the while loop.

i915 driver - enable opregion handle; program CADL.

add opregion handling for drm2 - which exposes some ACPI video configuration
pieces that some Lenovo laptop models use to flesh out which video device
to speak to.  This enables the brightness control in ACPI to work these models.

The CADL bits are also important - it's used to figure out which ACPI
events to hook the brightness buttons into.  It doesn't yet seem to work
for me, but it does for the OP.

Tested:

* Lenovo X230 (mine)
* OP: ASUS UX51VZ
