[PATCH v2 3/7] dt-bindings: riscv: cpus: document performance-domains property

[Joshua Yeong]

A CPU names the performance domain it runs in through the generic
"performance-domains" property of dvfs/performance-domain.yaml, which
gives the property its type and serves any performance domain provider.
The RISC-V CPU binding only allows the properties it lists, so list it
there, with one domain per CPU as the Arm CPU binding does.
