powerpc: Uncomment and make enable_kernel_vsx() routine available
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. Signed-off-by: Leonidas S.
