Fix thermal zone names for consistency with the other SoCs:
- GPU0 must be used as the first GPU item.
- SOCx deal with audio DSP, video, and infra subsystems.
The naming must be fixed "atomically" so compilation does not break.
As a result, the change is made in the dt-bindings and in the LVTS
driver within a single commit, despite the checkpatch warning.
The definitions can be modified safely here because they are used only
in the LVTS driver, which is modified accordingly.
