Timer clean-up to get us closer to moving timer code to drivers, 

and to get rid of CONFIG_OMAP_32K_TIMER and rely on the board
 or devicetree provided timer configuration.
 
 Note that these changes are on top of the recent timer fixes.

OMAP Counter-32K bindings
Required properties:
- compatible: Must be "ti,omap-counter32k" for OMAP controllers
- reg: Contains timer register address range (base address and length)
- ti,hwmods: Name of the hwmod associated to the counter, which is typically
"counter_32k"
Example:
counter32k: counter@4a304000 {
compatible = "ti,omap-counter32k";
reg = <0x4a304000 0x20>;

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.
- 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 0x400>;
interrupts = <95>;
ti,hwmods = "timer12"
ti,timer-alwon;
ti,timer-secure;
