crypto: vmx - Adding enable_kernel_vsx() to access VSX instructions
vmx-crypto driver make use of some VSX instructions which are only available if VSX is enabled. Running in cases where VSX are not enabled vmx-crypto fails in a VSX exception. In order to fix this enable_kernel_vsx() was added to turn on VSX instructions for vmx-crypto. Signed-off-by: NLeonidas S.
