watchdog: Octeon: Mark octeon_wdt interrupt as IRQF_NO_THREAD
This is to exclude it from force threading to allow RT patch set to work.
The watchdog timers are per-CPU and the addresses of register that reset
the timer are calculated based on the current CPU. Therefore we cannot
allow it to run on a thread on a different CPU. Also we only do a
single register write, which is much faster than scheduling a handler
thread.
And while on this line remove IRQF_DISABLED as this flag is a NOP.
