Merge tag 'rproc-v4.19' of git://github.com/andersson/remoteproc

Pull remoteproc updates from Bjorn Andersson:
 "This adds support for pre-start and post-shutdown hooks for remoteproc
  subdevices, refactors the Qualcomm Hexagon support to allow reuse
  between several drivers, makes authentication in the MDT file loader
  optional, migrates a few format strings to use %pK and migrates the
  Davinci driver to use the reset framework"
