[v5,0/6] Silvaco I3C master driver

Hello,

Here is the addition of a driver for the Silvaco I3C master IP.

Changes in v5:
* Added Rob's R-by when relevant.
* Fixed the robots warnings by pushing a little bit forward the changes in the
  mipi-hci binding file.
* Fixed the I3C master node name regex.
* Removed the redundant $ref: entries when the hz suffix is used.
* Simplified a little bit the regexes defining the child nodes.
* Updated the reg propertie description to better describe each entry.

Changes in v4:
* Converted the I3C binding file to yaml schema (including a license
  change, as requested by checkpatch.pl)
* Included this schema to the MIPI HCI binding file.
* Updated the Silvaco binding following Rob's review.
* No changes in the driver at all.

Changes in v3:
* Fix the MAINTAINERS file.
* Fix the bindings (clocks description, size-cells, etc)
* Add Rob's Ack on one patch.
* Dropped unnecessary locks.
* Used a hardware feature to automatically NACK IBI's during regular
  data transfers.
* Stopped flushing FIFOs (not needed).
* Entirely reworked the IBI handling logic.
* Dropped the warning when a device does not advertise it's dynamic
  address during an IBI.
* Moved the IBI logic into the master's workqueue instead of a
  threaded handler.
* Added a svc_i3c_master_readb() helper.
* Used consistent bit definitions (BIT() vs. FIELD_GET()).

Changes in v2:
* Change the manufacturer name from svc to silvaco.
