irqchip: irq-xtensa-mx: fix initial IRQ affinity
commit a255ee2 upstream. When irq-xtensa-mx chip is used in non-SMP configuration its irq_set_affinity callback is not called leaving IRQ affinity set empty. As a result IRQ delivery does not work in that configuration. Initialize IRQ affinity of the xtensa MX interrupt distributor to CPU 0 for all external IRQ lines.
