media: i2c: imx274: implement enum_mbus_code 



Current driver supports only SRGGB 10 bit RAW bayer format.
Add the enum_mbus_code implementation to report this format supported.

 # v4l2-ctl -d /dev/v4l-subdev3 --list-subdev-mbus-codes
ioctl: VIDIOC_SUBDEV_ENUM_MBUS_CODE (pad=0)
        0x300f: MEDIA_BUS_FMT_SRGGB10_1X10
