There's some useful info in efi_block_io_media that's only compiled in
at debug log level. While we need not print it always, it would be nice
to have this printed when doing devinfo. Add a custom devinfo callback
that does so and that invokes the normal EFI devinfo afterwards.
Defining DEBUG in the file will still print it early in probe as before.
