[PATCH v4 0/3] Move recovery/coredump configuration to sysfs

[Rishabh Bhatnagar]

>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. This patch series removes the recovery/coredump
entries from debugfs and moves them to sysfs. 
'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 build and "disabled" in
production builds. Whereas recovery needs to be "disabled" for
debugging purposes and "enabled" on production builds.

Changelog:

v4 -> v3:
- Remove the feature flag to expose recovery/coredump

v3 -> v2:
- Remove the coredump/recovery entries from debugfs
- Expose recovery/coredump from sysfs under a feature flag

v1 -> v2:
- Correct the contact name in the sysfs documentation.
- Remove the redundant write documentation for coredump/recovery sysfs
- Add a feature flag to make this interface switch configurable.
