scsi: ufs: exynos: Add check inside exynos_ufs_config_smu()

Browse source

commit c662cedea1 upstream.

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.
