2022-07-08phy: samsung-ufs: convert phy clk usage to clk_bulk APIChanho Park
Instead of using separated clock manipulation, this converts the phy clock usage to be clk_bulk APIs. By using this, we can completely remove has_symbol_clk check and symbol clk variables. Furthermore, clk_get should be moved to probe because there is no need to get them in the phy_init callback.

2022-06-08phy: samsung: ufs: remove drvdata from struct samsung_ufs_phyChanho Park
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.
