As far as I understand the problem, the imx93 A0 silicon was supposed to
have a functional auto-stop mode for the flexcan peripheral. But wakeup
stress tests show that it doesn't work reliable. So this and the
following patch switched the imx93 back to the "old" stop-mode via GPR,
which needs a DT update.

See the description of 63ead535570f for more details.
