dt-bindings: can: mpfs: document resets 



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.
