From: Phil Elwell <phil at raspberrypi.org>

Initialise the level for each IRQ to avoid a warning from the
arm arch timer code:

    arch_timer: WARNING: Invalid trigger for IRQ19, assuming level low
    arch_timer: WARNING: Please fix your firmware
    arch_timer: cp15 timer(s) running at 19.20MHz (virt).
