am7xxx-play: Replace deprecated FFmpeg API symbol PIX_FMT_NV12
PIX_FMT_NV12 is not going to be available in ffmpeg 2.9 so prepare for
that by using AV_PIX_FMT_NV12, which BTW has been available for quite
some time already.

am7xxx-modeswitch: fix the Length field in the switch command
The switch_command is a USB storage message, the bulk_cb_wrap structure
from include/linux/usb/storage.h in the Linux kernel shows the fields
meanings:
struct bulk_cb_wrap {
__le32 Signature; /* contains 'USBC' */
__u32 Tag; /* unique per command id */
__le32 DataTransferLength; /* size of data */
__u8 Flags; /* direction in bit 0 */
__u8 Lun; /* LUN normally 0 */
__u8 Length; /* length of the CDB */
__u8 CDB[16]; /* max command */
};
In switch_command the data in CDB is 16 bytes long (0x10), so using 0x0c
was wrong, it worked on some devices but it did not on others.
Use the correct value.
