Subject: [PATCH v3 06/14] scsi: ufs: exynos: Add EXYNOS_UFS_OPT_SKIP_CONFIG_PHY_ATTR check

The values calculated in exynos_ufs_specify_phy_time_attr() are only
used in exynos_ufs_config_phy_time_attr() which is only called if the
EXYNOS_UFS_OPT_SKIP_CONFIG_PHY_ATTR flag is not set.

Add a check for this flag to exynos_ufs_specify_phy_time_attr() and
return for platforms that don't set it.
