ARM: 6057/1: Realview: register PMU IRQs during board initialisation
This patch updates the initialisation routines for the Realview boards and the Versatile Express board [ca9x4 tile] so that they register their PMU IRQs with the PMU framework in the Kernel. Signed-off-by: Will Deacon <will.deacon@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
