Merge series "Compatible string consolidation for NXP DSPI driver" from Vladimir Oltean <olteanv@gmail.com>:
This series makes room in the driver for differentiation between the controllers which currently operate in TCFQ mode. Most of these are actually capable of a lot more in terms of throughput. This is in preparation of a second series which will convert the remaining users of TCFQ mode altogether to XSPI mode with command cycling.
