11eec5f5d8 Tiva Timer: Revert the previous change. Thre is a better way to handler timerout interrupts.
Removed setting of the initial timer interval load value (or, rather, it is always set to zero for a free-running timer).  Also, do not unconditional enable the timer out interrupt.  The timerout interrupt is not not enabled until tiva_timer32_setinterval() is called.
