Subject: [PATCH 6/7] scsi: ufs: exynos: remove tx_dif_p_nsec from exynosauto_ufs_drv_init()

Firstly exynosauto sets EXYNOS_UFS_OPT_SKIP_CONFIG_PHY_ATTR so setting
tx_dif_p_nsec has no effect.

Secondly this assignment can't get executed as samsung,sysreg dt property
is provided in for this platform. Meaning the execution flow will return on
regmap_update_bits call above.
