* There are three power modes defined:
* 1) MALI_POWER_MODE_ON
* 2) MALI_POWER_MODE_LIGHT_SLEEP
* 3) MALI_POWER_MODE_DEEP_SLEEP
* MALI power management module transitions to MALI_POWER_MODE_LIGHT_SLEEP mode when MALI is idle
* for idle timer (software timer defined in mali_pmm_policy_jobcontrol.h) duration, MALI transitions
* to MALI_POWER_MODE_LIGHT_SLEEP mode during timeout if there are no more jobs queued.
* MALI power management module transitions to MALI_POWER_MODE_DEEP_SLEEP mode when OS does system power
* off.
* Customer has to add power down code when MALI transitions to MALI_POWER_MODE_LIGHT_SLEEP or MALI_POWER_MODE_DEEP_SLEEP
* mode.
* MALI_POWER_MODE_ON mode is entered when the MALI is to powered up. Some customers want to control voltage regulators during
* the whole system powers on/off. Customer can track in this function whether the MALI is powered up from
* MALI_POWER_MODE_LIGHT_SLEEP or MALI_POWER_MODE_DEEP_SLEEP mode and manage the voltage regulators as well.
* @param power_mode defines the power modes
* @return _MALI_OSK_ERR_OK on success otherwise, a suitable _mali_osk_errcode_t error.
