cacheinfo: Use RISC-V's init_cache_level() as generic OF implementation
RISC-V's implementation of init_of_cache_level() is following
the Devicetree Specification v0.3 regarding caches, cf.:
- s3.7.3 'Internal (L1) Cache Properties'
- s3.8 'Multi-level and Shared Cache Nodes'
Allow reusing the implementation by moving it.
Also make 'levels', 'leaves' and 'level' unsigned int.
