[Buildroot] [PATCH] gst-fsl-plugins: fix build for kernel headers >= 3.10

[Gary Bisson]

This package couldn't build using a toolchain with kernel headers >=
3.10 because of the use of VIDIOC_DBG_G_CHIP_IDENT. As stated in
videodev2.h, this ioctl should never be used.

Yann, Thomas, all,
After looking at the source code it appears that nothing justifies the use of
that obsolete ioctl. Its only purpose is to get the video device name so this
patch actually removes those unnecessary calls.
Thanks,
Gary

+Subject: [PATCH] Remove use of obsolete VIDIOC_DBG_G_CHIP_IDENT
+
+This ioctl should never be used in application as
+stated in videodev2.h header.
+Moreover, its use in this plugin was very limited.
