scsi: ufs: exynos: Ensure consistent phy reference counts
ufshcd_link_startup() can call ufshcd_vops_link_startup_notify()
multiple times when retrying. This causes the phy reference count to
keep increasing and the phy to not properly re-initialize.
If the phy has already been previously powered on, first issue a
phy_power_off() and phy_exit(), before re-initializing and powering on
again.
