scsi: ufs: ufs-exynos: Change ufs phy control sequence

Since commit 1599069a ("phy: core: Warn when phy_power_on is called
before phy_init"), the following warning has been reported:

	phy_power_on was called before phy_init

To address this, we need to remove phy_power_on from exynos_ufs_phy_init()
and move it after phy_init. phy_power_off and phy_exit are also necessary
in exynos_ufs_remove().
