Add an Image Tree Source (`sc7180-trogdor.its`) describing the FIT

to be built with:

As mentioned in the cover letter, there is no desperate need to land
this. The FIT image created here is pretty much the same as what the
downstream build scripts for ChromeOS programmatically
produce. Switching over to this would have a few benefits:
* It makes it easy to use fdtfactor on the trogdor kernel image.
* It would set the path for future Chromebooks, and on those
Chromebooks maybe we could use the "description" of the
configurations to help the bootloader so we didn't need the awkward
piles of "compatible" strings that we have.
* It could potentially be useful to people in the community putting
upstream kernels on sc7180-trogdor devices.

This all being said, there's nothing terribly critical here, so if
it's controversial or people hate it then it's fine not to land it.

I would consider in this case to put it to any folder. There are a lot of dts/dtsi/dtso files in qcom folder. That having subfolder would be IMHO better structure.

Thanks,
