thermal: rcar: Document SoC-specific bindings

The documentation only mentioned the generic fallback compatible property.
Add the missing SoC-specific compatible properties, some of which are
already in use.

+                           - "renesas,thermal-r8a7791" (R-Car M2)
 - reg                  : Address range of the thermal registers.
                          The 1st reg will be recognized as common register
                          if it has "interrupts".
