Well, not really. Normally, the device tree for the global timer
should contain an irq declaration. We do not need it on omap4430
because drivers/clocksource/arm_gloabl_timer.c is badly hacked, but
the hack does not work on omap4460. The patch sent in another mail,
gets the hack also working on omap4460. But this is still a bad
hack.
