Max Filippov de23a6a1a3 irqchip: irq-xtensa-mx: fix initial IRQ affinity
commit a255ee29252066d621df5d6b420bf534c6ba5bc0 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.
