Move omap timer to drivers for 4.17

Browse source 
This series from Keerthy and Ladislav Michl move omap dmtimer code
 to drivers. As we don't want to export custom timer functions to
 random drivers, we also need to update the related PWM driver to
 pass the timer specific functions in platform data.
 
 Note that this series is based on a merge of omap1 specific timer
 fix and omap2+ platform data clean-up to keep things working and
 make the move a bit simpler.
