Convert the Texas Instruments DSP bindings to DT schema.
During the conversion, the following updates were made:
- Moved the binding to bindings/soc/ti/
- Make the 'ti,hwmods' property optional to resolve dtbs_check
warnings, as several in-tree device trees currently omit it.
A review of the ti-sysc driver (drivers/bus/ti-sysc.c)
shows that the property is not strictly required for probing.
The driver only reads it to populate the 'ddata->legacy_mode'
flag. If the property is absent, the probe sequence continues
normally without error.

Convert the Texas Instruments IVA bindings to DT schema.
During the conversion, the following updates were made:
- Moved the binding to bindings/soc/ti/
- Removed 'ti,iva' from the example as it is undocumented and
unused.
- Make the 'ti,hwmods' property conditionally required. Modern ti-sysc
deployments do not require it for probing, but older
OMAP2/3 platforms relying on omap_device.c still need it.
- Documented the 'dsp' child node, which is actively used in the OMAP3
device tree (omap3.dtsi) but was missing from the old txt binding.
