Sounds like this is related to an existing panic device we already
support. So what does enabling hv_crash do in QEMU? Is it an additional
channel to a panic device or is the panic device still needed even if
hv_crash is enabled? In any case, I think we should map this somehow to
the panic device instead of copying 1:1 the way QEMU enables hv_crash.
Just to make it clear, NACK until the design is sorted out.
