In preparation of adding DRM bridge support to the hdmi5 encoder code,
rework the EDID read to isolate data read.
The hdmi_read_edid() function is the main entry point. It performs all
initialisation steps required prior to reading the EDID (such as
ensuring the device is powered on), as well as corresponding cleanup
steps afterwards. EDID read itself is handled by hdmi_read_edid_data()
that calls the hdmi5_core_ddc_read() function to read individual blocks.
This new code architecture will allow reusing hdmi_read_edid() and
hdmi5_core_ddc_read() for the drm_bridge EDID read implementation, while
swapping out hdmi_read_edid_data() for the DRM drm_do_get_edid()

In order to support drm_bridge-based pipeline, the internal HDMI
encoders will need to expose the EDID read operation through the
drm_bridge API, and thus to expose a drm_bridge instance corresponding
to the encoder. The HDMI encoders are however handled as omap_dss_device
instances, which conflicts with this requirement.
In order to move forward with the drm_bridge transition, add support for
creating drm_bridge instances local to DSS outputs. If a local bridge is
passed to the omapdss_device_init_output() function, it is used as the
first bridge in the chain, and the omap_dss_device.next_bridge field is
set to the next bridge for the use of the internal encoders' bridges.

The DSS core looks up the next device connected to an output by
traversing the OF graph. It currently hardcodes the local port number to
0, which breaks any output with a different port number (SDI on OMAP3
and any DPI output but the first one). Fix this by repurposing the
currently unused of_ports bitmask in omap_dss_device with an of_port
output port number, and use it to traverse the OF graph.

Replace the manual panel handling code by a drm_panel_bridge. This
simplifies the driver and allows all components in the display pipeline
to be treated as bridges, paving the way to generic connector handling.

When the DSS initialises its output DPI and SDI ports, failures don't
clean up previous successfully initialised ports. This can lead to
resource leak or memory corruption. Fix it.

Most bridge drivers create a DRM connector to model the connector at the
output of the bridge. This model is historical and has worked pretty
well so far, but causes several issues:
- It prevents supporting more complex display pipelines where DRM
connector operations are split over multiple components. For instance a
pipeline with a bridge connected to the DDC signals to read EDID data,
and another one connected to the HPD signal to detect connection and
disconnection, will not be possible to support through this model.
- It requires every bridge driver to implement similar connector
handling code, resulting in code duplication.
- It assumes that a bridge will either be wired to a connector or to
another bridge, but doesn't support bridges that can be used in both
positions very well (although there is some ad-hoc support for this in
the analogix_dp bridge driver).
In order to solve these issues, ownership of the connector needs to be
moved to the display controller driver.
To avoid code duplication in display controller drivers, add a new
helper to create and manage a DRM connector backed by a chain of
bridges. All connector operations are delegating to the appropriate
bridge in the chain.

The tfp410 driver can operate as part of a pipeline where the
drm_connector is created by the display controller. Enable this mode of
operation by skipping creation of a drm_connector internally.

Now that a driver is available for display connectors, replace the
manual connector handling code with usage of the DRM bridge API. The
tfp410 driver doesn't deal with the display connector directly anymore,
but still delegates drm_connector operations to the next bridge. This
brings us one step closer to having the tfp410 driver handling the
TFP410 only.
