Description

powerpc: Bind IRQs to only one interrupt on QorIQ SoCs

The QorIQ SoCs don't actually support multicast interrupts, and the
references state explicitly that multicast is undefined behavior. Avoid the
undefined behavior by binding to only a single CPU, using a quirk to
determine if this is necessary.
