The clcd device is lacking an interrupt-parent property, which makes the interrupt unusable and shows up as a warning with the latest dtc version:

arch/arm/boot/dts/ste-nomadik-s8815.dtb: Warning (interrupts_property): Missing interrupt-parent for /amba/clcd@10120000 arch/arm/boot/dts/ste-nomadik-nhk15.dtb: Warning (interrupts_property): Missing interrupt-parent for /amba/clcd@10120000

I looked up the old board files and found that this interrupt has the same irqchip as all the other on-chip device, it just needs one extra line.
