dt-bindings: timer: sifive,clint: add legacy riscv compatible

While "real" hardware might not use the compatible string "riscv,clint0"
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: clint@2000000: compatible:0: 'sifive,clint0' is not one of ['sifive,fu540-c000-clint', 'starfive,jh7100-clint', 'canaan,k210-clint']
