Add fields spacing, level_min, level_max and level to struct v4l2_hw_freq_seek.
The level is used for determining which channels are considered receivable
during HW scan.
Add VIDIOC_G_HW_FREQ_SEEK to IOCTL codes. This is used for getting the minimum
and
maximum values for the level field in the v4l2_hw_freq_seek struct.
