/* VIDIOC_ENUMSTD on go7007 were used for enumerating the supported fps and
   its resolution, when the device is not connected to TV.
   This is were an API abuse, probably used by the lack of specific IOCTL's to
   enumerate it, by the time the driver was written.

   However, since kernel 2.6.19, two new ioctls (VIDIOC_ENUM_FRAMEINTERVALS
   and VIDIOC_ENUM_FRAMESIZES) were added for this purpose.

   The two functions below implement the newer ioctls
