thermal: rcar: enable to use thermal-zone on DT

Browse Source 
This patch enables to use thermal-zone on DT if it was calles as
"renesas,rcar-thermal-gen2".
Previous style (= non thermal-zone) is still supported by
"renesas,rcar-thermal" to keep compatibility for "git bisect".

* Renesas R-Car Thermal
Required properties:
- compatible : "renesas,thermal-<soctype>", "renesas,rcar-thermal"
as fallback.
- compatible : "renesas,thermal-<soctype>",
"renesas,rcar-gen2-thermal" (with thermal-zone) or
"renesas,rcar-thermal" (without thermal-zone) as fallback.
Examples with soctypes are:
- "renesas,thermal-r8a73a4" (R-Mobile APE6)
- "renesas,thermal-r8a7779" (R-Car H1)
