Some pll_sc_gate clocks need to wait a certain long time for being stable after enabled, for this reason enabling this kind of clocks shouldn't be done in clk_ops.enable() which would be called at interrupt context. So we move the operation to .prepare(), and also hooks to .unprepare() with disabling pll_sc_gate clocks.
