Provide an example of the usage of the DT bindings for TMIO
in their documentation. The example given is for the r8a7790 (R-Car H2).

v3
* Updated example to newer upstream DTS which uses newer CPG/MSSR bindings.

v2
* Correct description of example, it is for the r8a7790 (R-Car H2)
  rather than the r8a7779 (R-Car H1)
