Merge tag 'rproc-v4.9' of git://github.com/andersson/remoteproc

Pull remoteproc updates from Bjorn Andersson:
 "In addition to a slew of minor fixes and cleanups these patches
  refactor how we deal with remoteprocs that will be auto-booting
  themselves.

  That does clean up the remote resource handling but makes for
  additional work to clarify responsibilities and life cycles of
  resources. We also revise how module locking of remoteproc drivers
  work, so that they are locked as we hand out references to them to
  third parties, rather than only when booted by anyone.

  In addition to that we also introduce the Qualcomm Wireless Subsystem
  remoteproc driver"
