While being able to switch drivers without changing the DT by forcibly
binding a different driver would definitely be a nice feature, and
would have been possible with the older remoteproc-pru bindings, I
think it's a stretch to say this "needs" a solution. Right now, in
practice, selection between uio-pruss and remoteproc-pru is done
simply by modifying the device tree appropriately (typically by having
u-boot apply an overlay to the DT), and I don't think anyone views
this as unduly burdensome?
