But can they be cascaded from any clocks and irqs on the mainboard,
or just a few selected ones that are connected to the plug-in
module?

If you can describe which IRQs and clocks are routed to the
connector, then everything below it can be locally described
again. For the interrupts, you can use an
interrupt-map/interrupt-map-mask pair, and I'd assume for
the clocks, you just need to provide the right labels.
