This is porting mxc vout driver from imx_3.5.7 kernel to
imx_3.10 kernel.
* Put the driver in drivers/media/platform/ directory instead
of drivers/media/video/ directory, since the later one is
renamed to the former one in 3.10 kernel.
* Change the ipu-v3.h header file from <mach/ipu-v3.h> to
<linux/ipu-v3.h>.
* Change the mxc_vidioc_s_crop() function's implementation since
the definition of the vidioc_s_crop() function is modified to
make the last argument be constant.
* Set vfl_dir to be VFL_DIR_TX since the ioctrl validity checks
are improved in 3.10 kernel.
* Remove 'defaut y' setting for VIDEO_MXC_OUTPUT and
VIDEO_MXC_IPU_OUTPUT Kconfigs. They may be configured by kernel
default configure or by user.
* Make VIDEO_MXC_OUTPUT Kconfig depend on FB_MXC Kconfig since
we need framebuffers to be rendered.
* Make VIDEO_MXC_IPU_OUTPUT Kconfig be tristate.
* Split <linux/mxc_v4l2.h> header file up into include/linux/
and include/uapi/linux/ directories so that the userspace may
include the mxc_v4l2.h header file.
