[patch 036/198] ppc32: Fix mpc8xx watchdog

[akpm@osdl.org]

From: Tom Rini <trini@kernel.crashing.org>

The CONFIG_8xx_WDT option got broken in the generic hardirq update as ppc32
had its own different request_irq that worked when other arches used
setup_irq.  This is the trivial fix for the problem.
