Subject: [PATCH] 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.
