Since commit 489447380a29 ("[PATCH] handle errors returned by
platform_get_irq*()") ten years ago, the sa1111 driver refuses to
work without an interrupt line passed in its resources, so the
check for NO_IRQ is unnecessary.

I have also checked that all four machines files that register
an sa1111 device (lubbock, badge4, journada720, and neponset)
do set an interrupt line.
