clk: imx: pllv4: use prepare/unprepare
It is not good to use enable/disable for PLLv4 which needs time to lock, because enable/disable is expected to be able run in interrupt context. So use prepare/unprepare. Signed-off-by: Peng Fan <peng.fan@nxp.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
