Being able to upload u-boot over USB is rather useful, so ideally this
functionality should be enabled by the default config for these boards.
Currently however no USB support is built into the SPL nor is SDP
enabled for i.MX6 Sabre Auto boards.

The first two patches in this series adjust the defconfig in a similar
way as Fabio has done in a recent patchset for Sabre SD. The first one
drops SPL DM support as there is no way to fit that *and* USB support in
at the moment, the second one adds missing pinctrl configuration for the
main u-boot binary.

The third patch enabled USB & SPL SDP support.

Patch four adds support for loading FIT images over SDP as that is what
is in use for the Sabre auto's main u-boot image. This is simply the
patch Frieder Schrempf submitted to the mainlinglist earlier, but made
to build on current git master. (Frieder could you be so kind to add
your SoB?).

The final patch fixes the u-boot image failing to start due to DM_VIDEO.

Patchset tested by using uuu with the following configuration:
uuu_version 1.2
SDP: boot -f  SPL
SDPU: write -f u-boot-dtb.img -addr 0x10000000
SDPU: jump -addr 0x10000000
SPDU: done

I suspect these patches are to late for 2019.07, especially since FIT
support in SDP would be a new feature? If so I'm happy to split this set
out of patches that should definatly land for 2019.07 (Making sabre auto
work) and submit the others for 2019.10
