While "real" hardware might not use the compatible string "riscv,plic0"
it is present in the driver & QEMU uses it for automatically generated
virt machine dtbs. To avoid dt-validate problems with QEMU produced
dtbs, such as the following, add it to the binding.
riscv-virt.dtb: plic@c000000: compatible: 'oneOf' conditional failed, one must be fixed:
'sifive,plic-1.0.0' is not one of ['sifive,fu540-c000-plic', 'starfive,jh7100-plic', 'canaan,k210-plic']
'sifive,plic-1.0.0' is not one of ['allwinner,sun20i-d1-plic']
'sifive,plic-1.0.0' was expected
'thead,c900-plic' was expected
riscv-virt.dtb: plic@c000000: '#address-cells' is a required property
