dt-bindings: riscv: Document cbop-block-size

Browse Source 
Following the examples of cbom-block-size and cboz-block-size,
cbop-block-size is the cache size of Zicbop (cbo.prefetch) operations.
The most common case is to have all cache block sizes to be the same
size (e.g. profiles such as rva22u64 mandates a 64 bytes size for all
cache operations), but there's no specification requirement for that,
and an implementation can have different cache sizes for each operation.
