imx: i.mx6q: imx6q_logic: Migrate to SPL and enable SDP

Since the vast majority of i.MX6 boards are migrating to SPL,
this patch converts im6q_logic to SPL and enables the SDP for
loading SPL and u-boot.img over USB.  The Falcon mode only
supports NAND flash as of now due to limited space/RAM, but
all i.MX6D/Q SOM's from Logic PD have internal NAND from which
to boot.
