dt-bindings: can: rcar_can: document r8a77965 support

Browse source 
Document the support for rcar_can on R8A77965 SoC devices.
Add R8A77965 to the list of SoCs which require the "assigned-clocks" and
"assigned-clock-rates" properties (thanks, Sergei).

Required properties for R8A7795, R8A7796 and R8A77965:
For the denoted SoCs, "clkp2" can be CANFD clock. This is a div6 clock and can
be used by both CAN and CAN FD controller at the same time. It needs to be
scaled to maximum frequency if any of these controllers use it. This is done
using the below properties:
- assigned-clocks: phandle of clkp2(CANFD) clock.
