arch_topology: Silence early cacheinfo errors when non-existent
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.
Fixes: 3fcbf1c77d08 ("arch_topology: Fix cache attributes detection in the CPU hotplug path")
