This patch adds support to Audio for both adv7511 and adv7533
bridge chips.
This patch was originally from [1] by Lars-Peter Clausen <lars@metafoo.de>
and was adapted by Archit Taneja <architt@codeaurora.org> and
Srinivas Kandagatla <srinivas.kandagatla@linaro.org>.
Then I heavily reworked it to use the hdmi-codec driver. And also
folded in some audio packet initialization done by Andy Green
<andy.green@linaro.org>. So credit to them, but blame to me.

ADV7533 is a DSI to HDMI encoder chip. It is a derivative of ADV7511,
with additional blocks to translate input DSI data to parallel RGB
data. Besides the ADV7511 I2C register map, it has additional registers
that require to be configured to activate the DSI Rx block.
Create a new config that enables ADV7533 support. Use DT compatible
strings to populate the ADV7533 type enum. Add minimal register
configurations belonging to the DSI/CEC register map. Keep the ADV7533
code in a separate file.
Originally worked on by Lars-Peter Clausen <lars@metafoo.de>

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.
