0a2b56c8ce boot: Show an indication for encrypted bootflows
We don't support storing the OS on an encrypted partition, but in some
cases the root partition may be encrypted. Add an indication of this
when listing the bootflows.

ef117db9c3 expo: Store mouse pointer and size in expo
Store the mouse pointer image and its dimensions in the expo structure

b0025aa2b0 boot: Show the underlying bootflow device in the app
Within the app all media devices are 'efi' so it isn't useful to show
that as the media. Look up the media-type of the underlying device, e.g.
'usb' or 'nvme'. This is a lot more helpful, and can make it easy to see
which bootflows relates to internal media and which to external, for
example.

8c620fd504 boot: Consider non-bootable partitions

And a suggestion to just initialize bflow to NULL. This would however
would be ensuring a bad dereference. Instead, looking at the function we
rework things so that when CONFIG_EXPO is not enabled (and so, no UI) we
error early and would never reach this point in the code.  Simplify the
