Subject: [PATCH] x86: mmconf: fix section mismatch warning

WARNING: arch/x86/kernel/built-in.o(.cpuinit.text+0x1591): Section mismatch in reference from the function init_amd() to the function .init.text:check_enable_amd_mmconf_dmi()
The function __cpuinit init_amd() references
a function __init check_enable_amd_mmconf_dmi().
If check_enable_amd_mmconf_dmi is only used by init_amd then
annotate check_enable_amd_mmconf_dmi with a matching annotation.

check_enable_amd_mmconf_dmi is only called from init_amd which is __cpuinit
