As Dan pointed out, during validation, we have bisected this issue on
a dragonboard 410c (can't find root device) to the following commit
for v4.14:

[1ed3a9307230] rpmsg: core: add support to power domains for devices

There is an on-going discussion on "[PATCH] rpmsg: core: add support
to power domains for devices" about this patch having other
dependencies and breaking something else on v4.14 as well.

Do you think we could drop this patch, for now, in a possible -rc3 for
v4.14.72 ? Dragonboards aren't being tested, because of this, since
v4.14.70. Hopefully it isn't too late for this release =).

BTW, I have just tested removing the commit from -rc2 and the board boots okay.

Thank you
-Rafael
