media: staging/imx: Increase IMX_MEDIA_EOF_TIMEOUT

When trying to capture video on a imx6dl-based board with an ADV7280,
the following timeout error is observed:

v4l2-ctl --stream-mmap -d /dev/video2
[   22.792049] ipu1_csi1: EOF timeout
VIDIOC_DQBUF: failed: Input/output error

Increase the IMX_MEDIA_EOF_TIMEOUT to avoid such problem.
