Hmm, I'm a bit skeptical whether representing anything under /firmware
as a platform device is a good idea. Having a more structured way to
probe those seems like a good idea, but maybe a different subsystem
would be more appropriate.
I do realize that a 'platform_device' has become a rather generic abstraction
for almost anything, but at some point we might want to draw the line
of what is a platform_device.
