With some further experimentation I've found that making the esp/le
devices children of their respective espdma/ledma devices makes things a
lot cleaner.

I've also got another related patch to update the espdma/ledma
tracepoints to log the DMA transaction length, so I'll submit a v2 of
this with the additional changes shortly.
