Simplify DSI pin config, which always originates from DT
nowadays. With the code being fully contained in the DSI
encoder, we can drop the public structure.
Since the function is no longer exposed, it now directly
takes the private DSI data pointer. This drops a pointless
conversion and means the pins can be configured earlier.

This drops the virtual channel logic. Afterwards DSI clients
request their channel number and get the virtual channel with
the same number or -EBUSY if already in use.
The change here is not strictly speaking correct, as it combines the VC
(DSI's "configuration block") and virtual channel ID (the ID sent in the
DSI packets). But as we currently only support a single DSI command mode
panel, this works fine: we always use VC0, and VC ID 0.
This needs more work to support video mode panels, but that can be done
after moving to DRM bridge and panel model, after which we can do that
work with the proper APIs.

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.
