x86: Remove CPU cache size output for non-Intel too

As Dave Jones said about the output in intel_cacheinfo.c: "They
aren't useful, and pollute the dmesg output a lot (especially on
machines with many cores).  Also the same information can be
trivially found out from userspace."

Give the generic display_cacheinfo() function the same treatment.
