ANX6345 LVTTL->eDP video bridge, driver with device tree bindings.
Long time, few but important changes.

Changes since v3:

* converted binding schema file to json-schema ("YAML")
  It now validates (itself and the dts) like a charm ;-)
  Input port0 is mandatory, output port1 is optional.

* Enric Balletbo i Serra waived analogix-anx6345 module ownership to icenowy
  <CAFqH_50s0J_NEevV9b5o-wq-bw+xGaUZ3WyhVDRZKyM2Yn-iVg@mail.gmail.com>
  Since they both agree, I won't interfere.

Changes from v2:

* use SPDX-IDs throughout

* removed the panel output again, as it was not what Maxime had in mind.
  At least the Teres-I does very well without.

* binding clarifications and cosmetic changes as suggested by Andrzej

Changes from v1:

* fixed up copyright information. Most code changes are only moves and thus
  retain copyright and module ownership. Even the new analogix-anx6345.c originates
  from the old 1495-line analogix-anx78xx.c, with 306 insertions and 987 deletions
  (ignoring the trivial anx78xx -> anx6345 replacements) 306 new vs. 508 old...

* fixed all minor formatting issues brought up

* merged previously separate new analogix_dp_i2c module into existing analogix_dp

* split additional defines into a preparatory patch

* renamed the factored-out common functions anx_aux_* -> anx_dp_aux_*, because
  anx_...aux_transfer was exported globally. Besides, it is now GPL-only exported.

* moved chip ID read into a separate function.

* keep the chip powered after a successful probe.
  (There's a good chance that this is the only display during boot!)

* updated the binding document: LVTTL input is now required, only the output side
  description is optional.

 Laurent: I have also looked into the drm_panel_bridge infrastructure,
 but it's not that trivial to convert these drivers to it.

Changes from the respective previous versions:

* the reset polarity is corrected in DT and the driver;
  things should be clearer now.

* as requested, add a panel (the known innolux,n116bge) and connect
  the ports.

* renamed dvdd?? to *-supply to match the established scheme

* trivial update to the #include list, to make it compile in 5.2
