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.

+OMAP Timer bindings
+
+Required properties:
+- compatible: Must be "ti,omap2-timer" for OMAP2+ controllers.
+- reg: Contains timer register address range (base address and
+ length).
+- interrupts: Contains the interrupt information for the timer. The
+ format is being dependent on which interrupt controller
+ the OMAP device uses.
+- interrupt-parent The phandle for the interrupt controller that services
+ interrupts for this device.
+- ti,hwmods: Name of the hwmod associated to the timer, "timer<X>",
+ where <X> is the instance number of the timer from the
+ HW spec.
+
+Optional properties:
+- ti,timer-alwon: Indicates the timer is in an alway-on power domain.
+- ti,timer-dsp: Indicates the timer can interrupt the on-chip DSP in
+ addition to the ARM CPU.
+- ti,timer-pwm: Indicates the timer can generate a PWM output.
+- ti,timer-secure: Indicates the timer is reserved on a secure OMAP device
+ and therefore cannot be used by the kernel.
+
+Example:
+
+timer12: timer@48304000 {
+ compatible = "ti,omap2-timer";
+ reg = <0x48304000 0xfff>;
+ interrupts = <95>;
