Remove armhf support

Flash-kernel contains a database matching device-tree machine values with devicetree names.

There is no necessity to remove entries for architectures that are not supported in Ubuntu. We should try to minimize the differences to Debian. So setting this to won't fix for flash-kernel.

We have an Ubuntu-specific raspi kernel flavor raspi-nolpae which is amrhf only. That can be removed from the db, making the delta to Debian actually smaller. See the debdiff attached to bug 2051960.

As the Raspberry device-tree name does not depend on the flavor we should use kernel flavor 'any' in db.all.

Doesn't that mean that someone could install the generic arm64 kernel and render the device unbootable?

Indeed -- the Pi isn't compatible with our generic arm64 kernel, so we'll be sticking with the flavour limit for the time being, and this does actually reduce our delta with Debian. I've got a couple of other patches to incorporate into f-k this week, so I'm going to sponsor this as part of a larger upload but that should be fine for the devel series.
