* Description : Read current lifefime counter value.
* Lifetime timer is 64-bit timer which chains timer 0 and timer 1 together.
* So, timer 0 and 1 should by chained by calling PIT_HAL_SetTimerChainCmd
* before using this timer. The period of lifetime timer equals to "period of
* timer 0 * period of timer 1". For the 64-bit value, higher 32-bit will have
* the value of timer 1, and lower 32-bit have the value of timer 0.
