irqchip: Port the ARM IRQ drivers to GENERIC_IRQ_MULTI_HANDLER

GENERIC_IRQ_MULTI_HANDLER is incompatible with MULTI_IRQ_HANDLER because
they define the same symbols. Multiple generic irqchip drivers select
MULTI_IRQ_HANDLER, which is now defined on all architectures that
provide set_handle_irq().

To solve this select GENERIC_IRQ_MULTI_HANDLER for all drivers that used to
select MULTI_IRQ_HANDLER, but only when MULTI_IRQ_HANDLER doesn't exist.

After that every architecture can be converted over from MULTI_IRQ_HANDLER
to GENERIC_IRQ_MULTI_HANDLER before removing the extra MULTI_IRQ_HANDLER
scaffolding.
