armada_370_xp_msi_reenable_percpu is only defined when CONFIG_PCI_MSI
is enabled, and only called when SMP is enabled.

Without CONFIG_SMP, there are no callers, so we get a build time
warning instead:

drivers/irqchip/irq-armada-370-xp.c:319:13: error: 'armada_370_xp_msi_reenable_percpu' defined but not used [-Werror=unused-function]
  319 | static void armada_370_xp_msi_reenable_percpu(void) {}
      |             ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Mark the function as __maybe_unused to avoid adding more complexity
to the #ifdefs.

Fixes: 8ca61cde32c1 ("irqchip/armada-370-xp: Enable MSI affinity configuration")
