Subject: [PATCH 05/16] arch: x86: kernel: Make internal functions static in cpu/intel_cacheinfo.c

cpu/intel_cacheinfo.c defines two functions amd_get_l3_disable_slot
and amd_set_l3_disable_slot. No other file uses these functions.
So make these static.

This eliminates the following warnings:

arch/x86/kernel/cpu/intel_cacheinfo.c:349:5: warning: no previous prototype for ‘amd_get_l3_disable_slot’ [-Wmissing-prototypes]
arch/x86/kernel/cpu/intel_cacheinfo.c:427:5: warning: no previous prototype for ‘amd_set_l3_disable_slot’ [-Wmissing-prototypes]
