[net-next v1] dt-bindings: can: mpfs: document resets

[Conor Dooley]

From: Conor Dooley <conor.dooley at microchip.com>

The CAN cores on Polarfire SoC both have a reset. The platform firmware
brings both cores out of reset, but the linux driver must use them
during normal operation. The resets should have been made required, but
this is one of the things that can happen when the binding is written
without driver support.

Fixes: c878d518d7b6 ("dt-bindings: can: mpfs: document the mpfs CAN controller")

This is the second mistake in this binding, both spotted because of the
driver being written (although this one sat downstream for a while for
w/e reason). I wish I could say that I'd send the driver soon, but I am
busy upstreaming things I wrote and therefore understand at the moment,
so a driver that I'd have to go understand and review before sending is
low priority, sorry!
