ALSA: do not create OPL3 timers if there is no OPL3 irq wired

Most cards have OPL3 FM synthetiser but
they do not have OPL3 interrupt wired to
a sound chip or CPU.

Do not create OPL3 timers for such cards
as the timers are useless witthout interrupt.

This patch removes OPL3 timers for following
alsa drivers: snd-ad1816a, snd-opti93x,
snd-opti92x, snd-sc6000, snd-cmi8330.
