[PATCH 1/1] riscv: dts: microchip: correct L2 cache interrupts

The "PolarFire SoC MSS Technical Reference Manual" documents the
following PLIC interrupts:
1 - L2 Cache Controller Signals when a metadata correction event occurs
2 - L2 Cache Controller Signals when an uncorrectable metadata event occurs
3 - L2 Cache Controller Signals when a data correction event occurs
4 - L2 Cache Controller Signals when an uncorrectable data event occurs
This differs from the SiFive FU540 which only has three L2 cache related
interrupts.
The sequence in the device tree is defined by an enum:
enum {
DIR_CORR = 0,
DATA_CORR,
DATA_UNCORR,
DIR_UNCORR,
};
So the correct sequence of the L2 cache interrupts is
interrupts = <1>, <3>, <4>, <2>;

Fixes: 0fa6107eca41 ("RISC-V: Initial DTS for Microchip ICICLE board")
