Subject: 6.9-rc1 regression: irq: no irq domain found for interrupt-controller@c000000

The SiFive ccache driver fails to look up its irqs:

[ 0.762329] irq: no irq domain found for interrupt-controller@c000000 !
[ 0.769358] CCACHE: Could not request IRQ 0

This is fatal for the JH7100 based boards, since they depend on it for
their DMA noncoherence.
