Compiling the GICv3 driver on arm32 with CONFIG_SMP disabled
(CONFIG_ACPI is not available) generates an unused variable warning for
'broken_rdists'. Add a __maybe_unused attribute to silence the compiler.
Fixes: d633da5d3ab1 ("irqchip/gic-v3: Add support for ACPI's disabled but 'online capable' CPUs")
