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.

A hart context is a privilege mode in a hardware execution thread. For example,
in an 4 core system with 2-way SMT, you have 8 harts and probably at least two
