dt-bindings: timer: renesas: cmt: document R-Car gen3 support

Browse Source 
Document support for the R-Car gen3 CMT types 0/1 bindings -- they seem
to be the same CMT types 0/1 as in the R-Car gen2 SoCs.

Also document R8A779{7|8}0 bindings as these are the R-Car gen3 SoCs for
which the initial support was done.
