k210: dts: align plic node with Linux

The Linux PLIC interrupt-controller driver actually initializes the hart
context registers in the PLIC driver exactly in the same order as
specified in the interrupts-extended device tree property. See the device
tree binding [1].

The ordering of the interrupts is therefore essential in order to
configure the PLIC correctly.

Fix the order so that we will have sane IRQ behavior when booting Linux
with the u-boot device tree.
