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.

MMCSD SDIO: Add support for a new SDWAIT_WRCOMPLETE condition. The previous logic used a busy-wait loop to pool the card R1 start to determine when the card was ready for the next transfer. That busy-wait can be quite long -- hundreds of milliseconds. And alternative is to look the the SD D0 pin which will change state when the card is no longer busy.
...
This logic implements a change the avoids the busy-wait poll by reconfiguring the SD D0 pin as a GPIO interrupt, then waiting for the card to becom ready without taking up CPU cycles.
This change is conditioned on CONFIG_MMCSD_SDIOWATI_WRCOMPLETE and is currenlty only implemented for the STM32 SDIO driver.
