In some MTK SoC, we need set a encrypto enable bit MTK_SIP_KERNEL_HW_FDE_MSDC_CTL in secure world, so we use SMC call to finish it. But not every MTK SoC need to set this bit in secure world. This patch is for these SoCs. As for SMC call, we haven't found a proper way to deal with it, we'll do it later. Thanks, Mengqi.Zhang
