As the end goal is to have platform drivers split by vendor,
rename coda/ to chips-media/.

When building with CONFIG_VIDEO_CODA and CONFIG_CODA_FS enabled as
loadable modules, we see the following warning:
fs/coda/coda.ko
drivers/media/platform/coda/coda.ko
Rework so media/platform/coda is named coda-vpu. Leaving CODA_FS as is
since that's a well known module.

Remove the header search path to the current directory.
The compiler will search headers in the current directory by
using #include "..." instead of #include <...>
Also, change TRACE_INCLUDE_PATH to point to the location of trace.h.

The i.MX6 Video Data Order Adapter's (VDOA) sole purpose is to convert
from a custom macroblock tiled format produced by the CODA960 decoder
into linear formats that can be used for scanout.

Storing internal frames in macroblock tiled order improves memory
access patterns by allowing increased burst sizes when transferring
the uncompressed macroblocks to or from main memory.
The translation logic only supports a single chroma base address,
so this is only supported for the chroma interleaved NV12 format.
Since the rotator used to copy the decoder output into the v4l2
capture buffers does not seem to support the tiled format correctly,
only enable it in the encoder for now.

This patch adds tracepoints to the coda driver that can be used together
with the v4l2:v4l2_qbuf and v4l2:v4l2_dqbuf tracepoints to to follow video
frames through the mem2mem device.
For encoding with the BIT processor:
coda:coda_enc_pic_run
coda:coda_enc_pic_done
For decoding with the BIT processor:
coda:coda_bit_queue
coda:coda_dec_pic_run
coda:coda_dec_pic_done
coda:coda_dec_rot_done
Additionally, two low level tracepoints register whenever the BIT processor
is started and returns:
coda:coda_bit_run
coda:coda_bit_done

This patch adds JPEG encoding and decoding support for CODA7541,
using the BIT processor. Separate JPEG encoder and decoder video
devices are created due to different streaming behaviour and
different supported pixel formats.
The hardware can not change subsampling on the fly, but encode
and decode 4:2:2 subsampled JPEG images from and into this format.
The CODA7541 JPEG decoder uses the bitstream buffer and thus can run
without new buffers queued if there is a buffer in the bitstream.
Since there is no standard way to store the colorspace used in
JPEGs, and to make v4l2-compliance happy, the JPEG format always
reports V4L2_COLORSPACE_JPEG.

The coda driver has grown significantly and will continue to grow.
Move the coda driver into its own directory so it can be split.
Rename coda.h to coda_regs.h as it contains the register defines.
