irqchip: orion: Fix getting generic chip pointer.
commit d86e9af6336c0ad586a5dbd70064253d40bbb5ff upstream.
Enabling SPARSE_IRQ shows up a bug in the irq-orion bridge interrupt
handler. The bridge interrupt is implemented using a single generic
chip. Thus the parameter passed to irq_get_domain_generic_chip()
should always be zero.
