Disable some peripheral clocks when cpu starts

All peripheral clocks are default enabled after chip is powered on.
    When CPU starts, if reset reason is CPU reset, disable those clocks
    that are not enabled before reset. Otherwise, disable all those
    useless clocks.
    These peripheral clocks must be enabled when the peripherals are
    initialized and disabled when they are deinitialized.
