[PATCH 1/6] scsi: ufs: exynos: ensure pre_link() executes before exynos_ufs_phy_init()

[Peter Griffin <peter.griffin@linaro.org>]

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.
