Revert this patch since it depends on devicetree functionality that
previously has been reverted in the below commit.

Add the option to set the byteswap order in the devicetree. For the
official HDMI DIP for the NTC CHIP the byteswap order needs to be
RGB, however the driver sets it as BGR. With this patch the driver
will remain at BGR unless manually specified via devicetree.

drm_crtc.h has no need for linux/i2c.h, so don't include it.
Avoids useless rebuilds of the entire universe when
touching linux/i2c.h.
Quite a few placs do currently depend on linux/i2c.h without
actually including it directly. All of those need to be
fixed up.
v2: imx and mcde need linux/io.h for readl()/etc.

When validating a mode, bridges may need to do so in the context of a
display, as specified by drm_display_info. An example is the meson
dw-hdmi bridge that needs to consider the YUV 4:2:0 output format to
perform clock calculations.
Bridges that need the display info currently retrieve it from the
drm_connector created by the bridge. This gets in the way of moving
connector creation out of bridge drivers. To make this possible, pass
the drm_display_info to drm_bridge_funcs .mode_valid().
Changes to the bridge drivers have been performed with the following
coccinelle semantic patch and have been compile-tested.

This is a driver for video encoder with VGA and DVI/HDMI outputs.
There is no documentation for the chip -- the operation was guessed from
what was sniffed on a Dell Wyse 3020 ThinOS terminal, the register names
come from the ch7035 driver in Mediatek's GPL code dump.
Only bare minimum is implemented -- no fancy stuff, such as scaling. That
would only worsen our misery. We don't load the firmware and we don't need
to even bother enabling the MCU. There are probably no distributable
firmware images anyway.
Tested with a handful of monitors ranging from 1024x768@75 to 1400x1050@60,
with VGA as well as DVI.
