Uncomment VSX enable routine for instructions access

enable_kernel_vsx() was commented since anything was using it. It changes with vmx_crypto driver that call VSX instructions and need kernel_vsx enabled in order to do it properly. Without a way to enable VSX instruction vmx_crypto fails into an exception.

These patches uncomment enable_kernel_vsx() rountine and put it available for use. Also adds it in vmx_crypto in order to enable kernel_vsx before use VSX instructions.

Uncomment and make enable_kernel_vsx() routine available Adding enable_kernel_vsx() to access VSX instructions
