Move the EXYNOS_UFS_OPT_UFSPR_SECURE check inside exynos_ufs_config_smu().

This way all call sites will benefit from the check. This fixes a bug currently in the exynos_ufs_resume() path on gs101 as it calls exynos_ufs_config_smu() and we end up accessing registers that can only be accessed from secure world which results in a serror.
