Hi folks,
As you can see from the title, this series attempts to introduce/enable
RPROC support for the MX95-15x15-FRDM board.
For a while now, the imx_rproc driver has been using the reserved memory
DT nodes as the carveout names, which would force DT writers to go against
the DT specification's recommendation and use non-generic names (e.g.
"vdev0vring0", "vdev0vring1", etc...). This series also tries to fix this
issue by introducing the "memory-region-names" property and using it in
the imx_rproc driver to figure out the carveout names. The driver will
still allow the old way of doing things (i.e. no "memory-region-names"
property) but a warning will now be printed since this should be
discouraged.

Changes in v2:
* change commit message of binding patch to describe why it's needed
* drop restrictions on the string names passed via "memory-region-names"
* drop patch moving the CM7 node to the SoC DTSI. CM7 node is now added
in the RPMSG DT overlay
* rewrite commit message of patch removing some of the RMEM regions from
the bord DTS - previous version was a stale version from first iterations
of this series
* change "micfil" node status from "disabled" to "reserved"
* add check against rmem phandle count and string count mismatch
* include "of_reserved_mem.h" in "imx_rproc.h" to avoid having to rely on
the consumers including it
