[1/4,v6] drm/bridge: Add bindings for TI THS8134

Commit Message

This adds device tree bindings for the Texas Instruments
THS8134, THS8134A and THS8134B VGA DACs by extending and
renaming the existing bindings for THS8135.

These DACs are used for the VGA outputs on the ARM reference
designs such as Integrator, Versatile and RealView.

ChangeLog v5->v6:
- Fix the more-to-less specific compatible strings.
- Fix some speling.
- Collect Laurent's review tag.
ChangeLog v2->v5:
- Dropped the "ti,ths813x" as it turns out we need precise info
  about the sub-variant anyways as they all very in timings.
- Refine the THS8134 variants, it turns out ths8134, ths8134a
  and ths8134b are three different variants of ths8134.
ChangeLog v1->v2:
- Introduce specific-to-general compatible string:
  compatible = "ti,ths8134a", "ti,ths813x";
  so drivers can handle the whole family the same way.
- Collected Rob's ACK.
