The TDA998x is a HDMI transmitter with a TDA9950 CEC engine integrated
onto the same die. Add support for the TDA9950 CEC engine to the
TDA998x driver.

Add a CEC driver for the TDA9950, which is a stand-alone I2C CEC device,
but is also integrated into HDMI transceivers such as the TDA9989 and
TDA19989.
The TDA9950 contains a command processor which handles retransmissions
and the low level bus protocol. The driver just has to read and write
the messages, and handle error conditions.

Register ASoC HDMI codec for audio functionality and adds device tree
binding for audio configuration.
With the registered HDMI codec the tda998x node can be used like a
regular codec node in ASoC card configurations. HDMI audio info-frame
and audio stream header is generated by the ASoC HDMI codec. The codec
also applies constraints for available sample-rates based on Edid Like
Data from the display. The device tree binding document has been
updated [1].
Part of this patch has been inspired by Jean Francoise's "drm/i2c: tda998x:
Add support of a DT graph of ports"-patch [2]. There may still be some
identical lines left from the original patch and some of the ideas
have come from there.

The driver has been converted to use drm_bridge instead of
drm_i2c_slave_encoder. We can now move it to the bridge folder.
Create a separate folder since we already have a couple of files and
expect more when we support audio and ADV7533.
Rename the driver to adv7511_drv.c. This will come in handy later
when the driver module will need to be built from multiple object
files.

We don't want to use the old i2c slave encoder interface anymore.
Remove that and make the i2c driver create a drm_bridge entity instead.
Converting to bridges helps because the kms drivers don't need to
exract encoder slave ops from this driver and use it within their
own encoder/connector ops.
The driver now creates its own connector when a kms driver attaches
itself to the bridge. Therefore, kms drivers don't need to create
their own connectors anymore.
The old encoder slave ops are now used by the new bridge and connector
entities.
The of_node member in drm_bridge is accessible only when CONFIG_OF is
enabled. The driver anyway only works only when OF is available. Make
the driver depend on OF in its Kconfig.

This patch adds a driver for the Analog Devices adv7511. The adv7511 is
a standalone HDMI transmitter chip. It features a HDMI output interface
on one end and video and audio input interfaces on the other.

Move this out of nouveau directory. As we start to add more encoder
slaves used by other drivers, it makes sense to put the Kconfig bits in
one place.
