Add the 12 GP timers nodes present in OMAP2. Add the 12 GP timers nodes present in OMAP3. Add the 11 GP timers nodes present in OMAP4. Add the 7 GP timers nodes present in AM33xx. Add documentation for timer properties specific to OMAP. Thanks to Vaibhav Hiremath for creating the AM33xx timer nodes. I have modified Vaibhav's original nodes adding information on which timers support a PWM output.
