[PATCH v3 2/8] genirq: GENERIC_IRQ_IPI depends on SMP

[Samuel Holland <samuel@xxxxxxxxxxxx>]

The generic IPI code depends on the IRQ affinity mask being allocated
and initialized. This will not be the case if SMP is disabled. Fix up
the remaining driver that selected GENERIC_IRQ_IPI in a non-SMP config.
