arch/arm/src/tiva/Kconfig:
Remove EXPERIMENTAL dependency on TIVA_TIMER16_PWM.
arch/arm/src/tiva/common/tiva_timerlib.c:
Fix wrong 32/16-bit ifdef checks.
Add tiva_pwm16_sel_event() to choose GPTMCTL.TnEVENT value.
Implement tiva_pwm_mode16().
tiva_timer16_setinterval(): Fix wrong check for TIMER16_MODE_ONESHOT
and TIMER16_MODE_PERIODIC. Was comparing to config->cmn.mode
which can never have those values. This prevented interrupts being
enabled. Compare to timer->mode instead.
Add tiva_timer16pwm_setperiodduty() to set initial period, duty cycle,
and enable interrupts if requested in GPTM peripheral. Interrupts
are not enabled in NVIC until tiva_timer16_start() is called.
Add tiva_timer16pwm_setduty() to update duty cycle at any time.

arch/arm/src/tiva/hardware/tm4c/tm4c129_timer.h:
Add missing defines; make surrounding defines consistent.
arch/arm/src/tiva/tiva_timer.h:
Add new TIMER_FLAG_* configuration flags to enable configuring the
16-bit PWM feature. Extend type of "flags" in tiva_timer32config_s
and tiva_timer16config_s from 8- to 32-bits to allow more flags.
