Add initial HDK855 dts, based on sm8150-mtp, with a few changes.
Happy to see this on the list Jonathan, just some minor things on the
remoteproc nodes below.

One day we should stop being surprised by this and drop the "Apparently"
from this comment ;)
Had this copied from sm8150-mtp, dropped the comment entirely (to match
sm8250-mtp dts).

It would be nice to see a
firmware-name = "qcom/sm8150/adsp.mbn";
here. Because if we ever end up pushing firmware to linux-firmware this
DTB would continue to work.
Use https://github.com/andersson/pil-squasher to get mbn files out of
the mdt+bXX files for your testing (or just rename/symlink the mdt to
mbn for now).
Added the firmware-name fields as you suggested. One thing to note (it
shouldn't matter for HDK), these firmwares can be modified by the device
maker, so not all sm8150 will have the same adsp/cdsp/slpi firmware.
