Cc: Krzysztof Kozlowski, Romain TISSERAND
DSI panels can be placed under DSI bus directly and some of the Linux DRM
drivers will work fine with it: mipi_dsi_host_register() adds device for
such panel and DRM driver does not use OF graph to configure lanes.
Examples are Samsung Exynos and Allwinner DRM drivers.
The Linux panel drivers affected here do not use OF graph, either.
Requiring graph port for such panels is tying the binding to one
specific implementation of Linux DRM drivers, e.g. Qualcomm DRM which
requires the port. That's a mistake, because:
1. It prevents usage of such panel in DTS for other platforms,
2. Places the constraint (port requirement) in wrong domain - the DSI
host needs the port, not the panel.
The port is not needed for the panel hardware to operate thus it should
be optional.

dt-bindings: display: panel: Make DSI panels port optional
This commit removes the port property from the required list in several
DSI display panel Device Tree binding schemas so that panels placed
directly under a DSI bus node do not require an OF graph port.

[Severity: Low]
Should port remain required in the conditional then branch for
rocktech,rk050hr345-ct106a?
While densitron,dmt028vghmcmi-1d and ortustech,com35h3p70ulc are MIPI-DSI
panels, rocktech,rk050hr345-ct106a is an SPI-controlled DPI/RGB panel
(registered with DRM_MODE_CONNECTOR_DPI in ili9806e_spi_probe()). Because
its node sits under an SPI controller rather than a DSI host, the RGB
display controller still needs the OF graph port to link to the panel.
