[0/5] v3u: add support for RAVB

Message

Here is the series to enable RAVB on V3U. I took the DTS patches
from the BSP, the rest was developed on mainline tree. Note that only
RAVB0 could be tested because the other ones did not have PHYs attached.

Also, the last patch is a workaround. 'reset-gpios' cannot be obtained
currently which makes the driver fail. The problem is that
pinctrl_ready_for_gpio_range() returns EPROBE-DEFER. I hope Geert has an
idea because I got lost in the GPIO and V3U pinctrl details there. It
seems more of a PFC/CPG/GPIO problem to me.

Without the reset-gpio, the driver binds to avb0 and I can ping the host
successfully. So, I think at least the first three patches are ready.

Let me know your thoughts!

All the best,

   Wolfram
