From: Conor Dooley <conor.dooley@xxxxxxxxxxxxx>
PolarFire SoC does not have the same l2 cache controller as the fu540,
featuring an extra interrupt. Appease the devicetree checker overlords
by adding a PolarFire SoC specific compatible to fix the below sort of
warnings:
mpfs-polarberry.dtb: cache-controller@2010000: interrupts: [[1], [3], [4], [2]] is too long
Fixes: 0fa6107eca41 ("RISC-V: Initial DTS for Microchip ICICLE board")
Fixes: 34fc9cc3aebe ("riscv: dts: microchip: correct L2 cache interrupts")
