Sorry it will be slow going for this one.. I think we should initially
just make it use include/linux/platform_data/pwm_omap_dmtimer.h and
pdata-quirks.c. It seems we need to add few new functions there.

Then once it's working again, we can continue to make it use hrtimer
for one of the gptimers. Then after that it should be easy to change
it to use the PWM framework with the pwm_omap_dmtimer.
