powerpc: Uncomment and make enable_kernel_vsx() routine available
commit 72cd7b44bc99376b3f3c93cedcd052663fcdf705 upstream.
enable_kernel_vsx() function was commented since anything was using
it. However, vmx-crypto driver uses VSX instructions which are
only available if VSX is enable. Otherwise it rises an exception oops.
This patch uncomment enable_kernel_vsx() routine and makes it available.
