Since we needs to delay ~1ms to wait for 480MHz output clock of USB2 PHY to become stable after turn on it, the delay time is pretty long for something that's supposed to be "atomic" like a clk_enable(). Consider that clk_enable() will disable interrupt and that a 1ms interrupt latency is not sensible. The 480MHz output clock should be handled in prepare callbacks which support gate a clk if the operation may sleep.
