The creation of the I/O clock domain requires some adjustments.  Since
the watchdog counters are clocked by the I/O clock, use its rate for
timing calculations.

Add missing #inclusions of <linux/irq.h> to a whole bunch of files that should
really include it.  Note that this can replace #inclusions of <asm/irq.h>.

This is required for the patch to sort out irqflags handling function naming to
compile on MIPS.

The problem is that these files require access to things like setup_irq() -
which isn't available by #including <linux/interrupt.h>

The OCTEON is a MIPS64 based SOC family with an on chip watchdog unit.

The driver is split into two source files one for the C code and one
for assembly.  Assembly is needed to handle the NMI and then print the
machine state before the reboot is triggered.
