Subject: [PATCH 09/13] net: ravb: Make reset controller support mandatory

From: Claudiu Beznea <claudiu.beznea.uj@...renesas.com>

On RZ/G3S SoC the reset controller is mandatory for the IP to work.
The device tree binding documentation for ravb driver specifies that the
resets are mandatory. Based on this make the resets mandatory also in
driver for all ravb devices.
