arch_topology: Silence early cacheinfo errors when non-existent

Browse Source 
Architectures which do not have cacheinfo such as ARM 32-bit would spit
out the following during boot:

 Early cacheinfo failed, ret = -2

Treat -ENOENT specifically to silence this error since it means that the
platform does not support reporting its cache information.
