[PATCH v1 1/6] dt-bindings: riscv: cpus: add a ref the common cpu schema

[Conor Dooley <conor@kernel.org>]

From: Conor Dooley <conor.dooley@microchip.com>

To permit validation of RISC-V cpu nodes, "additionalProperties: true"
needs to be swapped for "unevaluatedProperties: false". To facilitate
this in a way that passes dt_binding_check, a reference to the cpu
schema is required.

Disallow the generic cache-op-block-size property that that drags in,
since the RISC-V CBO extensions do not require a common size, and have
individual properties.
