devel: DTBs have moved into vendor specific directories on arm64

[Andy Whitcroft]

[ SRU Justification ]
For trusty, the lts-vivid debian-installer builds install the lts-vivid kernel, which has the DTBs in the new location. As such, both d-i and f-k need fixing to look for the correct locations.

[ Test Case ]
For d-i, the test case is to build d-i and ensure it's picking up the right DTBs for both old and new location builds.

For f-k, the test case is to do an installation of both lts-utopic and lts-vivid on arm64 and ensure that flash-kernel is operating on the DTBs without error in both cases.

[ Regression Potential ]
The d-i change has already been tested in a PPA and is known-good, while the f-k change is a straight cherry-pick from vivid, where it was known to work, so both should be minimally scary.

[ Original Report ]
The installed DTBs have moved into vendor specific directories. We need to 1) make sure we are hoovering them up right, and 2) that the consumers thereof (d-i etc) are consuming them in the new locations.

NOTE: this actually is only _installed_ into those new directories on arm64.

[Andy Whitcroft (apw)]

As this only affects arm64, and we do not yet currently use any dtbs in the installer on that arch, we are safe to ignore this.

[Adam Conrad (adconrad)]

This will need fixing in trusty's flash-kernel and trusty's lts-v (and beyond) d-i builds as well.
