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)
