dt-bindings: update sifive plic compatible string
Add the compatible string "canaan,k210-plic" to the Sifive plic bindings
to indicate the use of the "sifive,plic-1.0.0" IP block in the Canaan
Kendryte K210 SoC. The description is also updated to reflect this
change, that is, that SoCs from other vendors may also use this plic
implementation.
