 * Function Name : pit_hal_read_lifetime_timer_count
 * 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_configure_timer_chain
 * 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.
