The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

of_graph_get_remote_node() returns remote device nodepointer with
refcount incremented, we should use of_node_put() on it when done.
Add missing of_node_put() to avoid refcount leak.

Support YUV422 output from the Amlogic Meson SoC VPU to the HDMI
controller. Without this YUV422 format out of the HDMI encoder
leads to using the dw-hdmi YUV444 to YUV422 color conversion which
gives wrong colors and a green line on the left edge of the screen.

This implements the necessary change to no more use the embedded
connector in dw-hdmi and use the dedicated bridge connector driver
by passing DRM_BRIDGE_ATTACH_NO_CONNECTOR to the bridge attach call.
The necessary connector properties are added to handle the same
functionalities as the embedded dw-hdmi connector, i.e. the HDR
metadata, the CEC notifier & other flags.
The dw-hdmi output_port is set to 1 in order to look for a connector
next bridge in order to get DRM_BRIDGE_ATTACH_NO_CONNECTOR working.

This moves all the non-DW-HDMI code where it should be:
an encoder in the drm/meson core driver.
The bridge functions are copied as-is, except:
- the encoder init uses the simple kms helper
- the mode_set has been moved to atomic_enable()
- debug prints are converted to dev_debg()
For now the bridge attach flags is 0, DRM_BRIDGE_ATTACH_NO_CONNECTOR
will be handled later.
The meson dw-hdmi glue is slightly fixed to live without the
encoder in the same driver.
