add mediabus formats and pixel formats supported
as part of dm365 vpfe device.
The device supports media formats(transfer and storage)
which include-
1: ALAW compressed bayer.
2: UV interleaved without Y (for resizer).
3: YDYU
Changes for v8:
1: Fixed a comment from Sakari, removed extra space.
Changes for v7:
1: Fixed a comment from Laurent, removed subscript for
dummy tags.
2: Fixed a comment from Sakari, used the same order for
ALAW pix fmt according to Documentation/video4linux/4CCs.txt.
Changes for v6:
1: Fixed a comment from Hans, replaced "YUYDYDYV and YVYDYDYU"
to "YUYDYVYD and YVYDYUYD".
Changes for v5:
1: Fixed comment from Laurent, moved ALAW format above DPCM
format to keep the alphabetically sorted, grouped textual
description for ALAW and DPCM compression, as they're mutally
exclusive, Changed V4L2_MBUS_FMT_YDYC8_1X16 to
V4L2_MBUS_FMT_YDYUYDYV8_1X16.
Changes for v4:
1: Rebased the patch set on Sakari's branch
(http://git.linuxtv.org/sailus/media_tree.git/shortlog/refs/heads/media-for-3.4)
mainly because of this patch
<URL:http://www.spinics.net/lists/linux-media/msg44871.html>
2: Fixed comments from Sakari, changed description for
UV8, and re-arranged &sub-uv8; in
Documentation/DocBook/media/v4l/pixfmt.xml file.
Changes for v3:
1: Added 4cc code for A-law compressed format as per
specified in documentation,
http://www.spinics.net/lists/linux-media/msg43890.html
Changes for v2:
1: Added entries in subdev-formats.xml for
V4L2_MBUS_FMT_YDYC8_1X16, V4L2_MBUS_FMT_UV8_1X8,
V4L2_MBUS_FMT_SBGGR10_ALAW8_1X8,
V4L2_MBUS_FMT_SGBRG10_ALAW8_1X8,
V4L2_MBUS_FMT_SGRBG10_ALAW8_1X8,
V4L2_MBUS_FMT_SRGGB10_ALAW8_1X8.
2: Added documentation of ALAW and UV8 pix format.

add new enum entries for supporting the media-bus formats on dm365.
These include some bayer and some non-bayer formats.
V4L2_MBUS_FMT_YDYUYDYV8_1X16 and V4L2_MBUS_FMT_UV8_1X8 are used
internal to the hardware by the resizer.
V4L2_MBUS_FMT_SBGGR10_ALAW8_1X8 represents the bayer ALAW format
that is supported by dm365 hardware.

add new macro V4L2_PIX_FMT_SGRBG10ALAW8 and associated formats
to represent Bayer format frames compressed by A-LAW algorithm,
add V4L2_PIX_FMT_UV8 to represent storage of CbCr data (UV interleaved)
only.
