ARM: omap2plus: convert to CONFIG_MULTI_IRQ_HANDLER
Convert the omap2plus platforms to be using CONFIG_MULTI_IRQ_HANDLER. Each machine is modified to provide either omap2_intc_handle_irq(), omap3_intc_handle_irq() or gic_handle_irq(). This allows for a major cleanup, removing the MULTI_OMAP setup from the interrupt path. Tested on both Panda and IGEPv2 (single kernel image) Tested-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
