scsi: ufs: exynos: remove tx_dif_p_nsec from exynosauto_ufs_drv_init()

Remove the assignment of tx_dif_p_nsec as both users of
exynosauto_ufs_drv_init() function (exynosauto and gs101) set the
EXYNOS_UFS_OPT_SKIP_CONFIG_PHY_ATTR flag meaning that tx_dif_p_nsec has
no effect.

Additionally both users also set the samsung,sysreg dt property, meaning
the execution flow will always return on the regmap_update_bits() call
before the assignment.
