This patch adds support for the three new SDR formats. These formats
were prefixed with "sliced" indicating I data constitutes the top half and
Q data constitutes the bottom half of the received buffer.
V4L2_SDR_FMT_SCU16BE - 14-bit complex (I & Q) unsigned big-endian sample
inside 16-bit. V4L2 FourCC: SC16
V4L2_SDR_FMT_SCU18BE - 16-bit complex (I & Q) unsigned big-endian sample
inside 18-bit. V4L2 FourCC: SC18
V4L2_SDR_FMT_SCU20BE - 18-bit complex (I & Q) unsigned big-endian sample
inside 20-bit. V4L2 FourCC: SC20
