[U-Boot] [PATCH v5 08/18] dm: clk: Define clk_get_parent() for clk operations

This commit adds the clk_get_parent() function, which is responsible for getting the parent's struct clock pointer. U-Boot's DM support for getting parent is different (the parent relationship is in udevice) than the one in Common Clock Framework [CCF] in Linux. To obtain the pointer to struct
