[PATCH v4 02/22] irqchip: Orion: Fix getting generic chip pointer.

From: Jason Cooper <hidden>

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.
