From Android R onwards Google has restricted access to debugfs in user
and user-debug builds. This restricts access to most of the features
exposed through debugfs. 'Coredump' and 'Recovery' are critical interfaces
that are required for remoteproc to work on Qualcomm Chipsets. Coredump
configuration needs to be set to "inline" in debug/test builds and
"disabled" in production builds. Whereas recovery needs to be "disabled"
for debugging purposes and "enabled" on production builds. Moving these
interfaces to sysfs will allow usage for these interfaces for 
production and debug builds.

  remoteproc: Move coredump entry from debugfs to sysfs.
  remoteproc: Move recovery debugfs entry to sysfs
