scsi: ufs: exynos: Ensure pre_link() executes before exynos_ufs_phy_init()
Ensure clocks are enabled before configuring unipro. Additionally move
the pre_link() hook before the exynos_ufs_phy_init() calls. This means
the register write sequence more closely resembles the ordering of the
downstream driver.
