Subject: powerpc/pmac/smp: Avoid unused-variable warnings
From: Ilie Halip <ilie.halip@xxxxxxxxx>
commit 9451c79bc39e610882bdd12370f01af5004a3c4f upstream.
When building with ppc64_defconfig, the compiler reports
that these 2 variables are not used:
warning: unused variable 'core99_l2_cache' [-Wunused-variable]
warning: unused variable 'core99_l3_cache' [-Wunused-variable]
They are only used when CONFIG_PPC64 is not defined. Move
them into a section which does the same macro check.

[mpe: Move them into core99_init_caches() which is their only user]
