Add 64-bit DMA support in the XHCI controller driver.

Merge the Cavium Octeon SDK 2.3.0 Simple Executive code and update FreeBSD to
make use of it where possible.

This primarily brings in support for newer hardware, and FreeBSD is not yet
able to support the abundance of IRQs on new hardware and many features in the
Ethernet driver.

Because of the changes to IRQs in the Simple Executive, we have to maintain our
own list of Octeon IRQs now, which probably can be pared-down and be specific
to the CIU interrupt unit soon, and when other interrupt mechanisms are added
they can maintain their own definitions.

Remove unmasking of interrupts from within the UART device now that the
function used is no longer present in the Simple Executive. The unmasking
seems to have been gratuitous as this is more properly handled by the buses
above the UART device, and seems to work on that basis.

- Properly set IRQ handlers for all USB ports

Unbreak the OCTEON1 kernel build after r228483 removing the left over
declaration.

Implement better support for USB controller suspend and resume.

This patch should remove the need for kldunload of USB
controller drivers at suspend and kldload of USB controller
drivers at resume.

This patch also fixes some build issues in avr32dci.c

Rename device_delete_all_children() into device_delete_children().

- There's no need to overwrite the default device method with the default
one. Interestingly, these are actually the default for quite some time
(bus_generic_driver_added(9) since r52045 and bus_generic_print_child(9)
since r52045) but even recently added device drivers do this unnecessarily.
Discussed with: jhb, marcel
- While at it, use DEVMETHOD_END.
Discussed with: jhb
- Also while at it, use __FBSDID.

Remove unneeded includes of <sys/linker_set.h>. Other headers that use
it internally contain nested includes.

o) Add the "octusb" controller which supports the first port of the Octeon
on-board USB controller. It is not currently enabled because there are
known problems with device communication and until those are fixed I am not
certain that it won't destabilize the system. [1]
o) Add the "cryptocteon" opencrypto device based on the OCF device written by
David McCullough. It is not currently enabled because until support for
saving/restoring coprocessor 2 state on context switch is available, it runs
with interrupts disabled, which tends to pessimize performance over using a
software crypto facility. Tests using this driver which are not negatively
affected by it running with interrupts disabled show it to be substantially
faster than software for large blocks.
