dt-bindings: ti-sysc: Update binding for timers and capabilities

The ti-sysc binding does not yet describe the capabilities of the
interconnect target module. So to make the ti-sysc binding usable
for configuring the interconnect target module, we need to add few
more properties:

1. To detect between omap2 and omap4 timers, let's add compatibles
   for them for "ti,sysc-omap2-timer" and,sysc-omap4-timer". This
   makes it easier to pick up the already initialized system timers
   later on

2. Let's add "ti,sysc-mask" for a mask of features supported by the
   interconnect target module. This describes what we have available
   in the various SYSCONFIG registers

3. Let's add "ti,sysc-midle" and "ti,sysc-sidle" lists for the master
   and slave idle modes supported by the interconnect target module.
   These describe the values available for MIDLE and SIDLE bits in
   the SYSCONFIG registers

4. Some interconnect target modules need a short delay after reset
   before they can be accessed, let's use "ti,sysc-delay-us" for
   that

5. Let's add "ti,syss-mask" bit to describe the optional SYSSTATUS
   register bits for reset done bits

6. Let's support the two existing custom quirk properties already
   listed in Documentation/devicetree/bindings/arm/omap/omap.txt for
   "ti,no-reset-on-init" and "ti,no-idle-on-init"

7. And finally, let's add a header for the binding for the dts
   files and the driver to use
