[PATCH v4 4/5] phy: samsung: ufs: remove drvdata from struct samsung_ufs_phy

[Chanho Park <chanho61.park@xxxxxxxxxxx>]

To change an offset of pmu_isol, we need to store its data instead of
having drvdata's pointer. The definition of the pmu_isol structure
should be extracted from samsung_ufs_phy_drvdata and rename the name
with samsung_ufs_phy_ prefix.
