Implement splassert() on mips64.

Adjust interrupt priority levels on mips64 so that priorities
of soft interrupts are lower than priorities of hard interrupts.
This allows the delivery of hard interrupts while soft interrupts
are masked.

Remove struct intrhand. It is no longer used on octeon.

Let each interrupt controller driver choose how to implement
intr_barrier(9).

With this change, the barrier should finally work properly with
cnmac(4) interrupts that have been assigned to secondary cores.

Remove unused spllock().

Give the FDT interrupt API a more generic naming by replacing the
arm_intr_* prefix with fdt_intr_*.

Include <sys/mutex.h> instead of <machine/mutex.h>

required by upcoming MI mutex change.

Assign each cnmac(4) port its own input work group, and assign
the interrupt processing of each work group to one of the available
CPUs. This enables some parallelism in the early stages of packet Rx.

Add a workaround that allows the use of sys/dev/fdt code on octeon.

OK kettenis@

Remove leftovers of a past softintr mechanism.

OK mpi@, kettenis@

Split octeon interrupt code into a glue layer and a CIU driver.
This makes possible to add drivers for other interrupt controllers
on the platform.

The glue layer has been derived from arm64/armv7.

Drop unnecessary call to octeon_setintrmask(). The function gets called
by the splx() handler.

Define register_splx_handler() in one place.

Extend the fdt interrupt API a little.

Add a routine for setting up interrupt handlers using fdt.

Rename mips64's trap_frame into trapframe.

For coherency with other archs and in order to use it in MI code.

Let MP-safe interrupt handlers run without the kernel lock on octeon.

intr_barrier(9) for loongson, octeon and sgi.

unify the mutex implementations on all the mips64 platforms.

this basically copies the sgi implementation to mips64 and removes
it from the rest. this way they get an optimised UP mutex implementation
and correct asserts on all platforms.
