There are a number of Pine64 devices which need the various files shipped by
raspi-firmware in the `/lib/firmware/brcm` directory.
I've now tried to install this package on both a Rock64 and a Quartz64 Model A
and the installation indeed failed:

```sh

While I now do have those files in ``/lib/firmware/brcm/`` it caused various
error which will only go away if I uninstall this package again.
And as expected, at least the assumption that ``/boot/firmware`` is present
(and being a mountpoint?) is incorrect, which causes the package installation
to fail, but it seems to also break any kernel related actions?
So I've increased the severity to 'serious'.
