dt-bindings: can: rcar_can: document r8a77990 support

Document the support for rcar_can on R8A77990 SoC devices.
Add R8A77990 to the list of SoCs which require the "assigned-clocks"
and "assigned-clock-rates" properties.

 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
