* system uptime gets corrupted with overflow in slow clock.
*
* Problem description
* During power collapse, APPS sleep time is calculated using slow clock
* ticks. The calculation of sleep time does not considers slow clock
* overflow and thus If slow clock overflows during suspend state then we
* get wrong sleep time and thus system uptime values gets corrupted.
* earlier sleep time was calculates as follows:
* sleep = current_sclk_tick - suspend_state_sclk_tick
*
* Failure frequency: Occasionally
* Scenario frequency: Uncommon
* Change description
* Modified the sleep time calculation to include slow clock overflow as follows:
* Now sleep time is calculated as:
* sleep = Maximum_sclk_tick_val - suspend_state_sclk_tick + current_sclk_tick.

* Added change to modify tick_at_suspend (variable that stores time tick

* Setting the suspend mode variable in case alarm time expires the current
* RTC time as in thic case also system enters suspend mode.
* to sdcc irq handlers returning IRQ_NONE without handling the interrupt.
