remoteproc: Allow platform-specific drivers to request resources

Once this patch-set has been applied; platform-specific remoteproc
drivers will be able to amend existing resource table entries,
provide new entries to be appended to an existing resource table
(if one already exists), start a new resource table (if one does
not already exist), and dump out resource table contents during
development/debugging.  It will also be possible to start remote
processors which do not require a resource table without being
forced to provide a fake one.

We're also taking the liberty to provide some simple fix-ups.

V2 is rebased on "auto-boot" series. It also includes following addons:
- associate an action to the resource request. This allows platform-specific
  driver to verify firmware resources, update or append resources in firmware
  resource table or create a local resource table.
- introduce spare resource to define room for resource table extension
- centralize resource table sanity checks.

V3 is rebased on remoteproc kernel 4.9 pull request. It integrates following
modifications:
- split patches per features
- fix Lee Jones's comments
- remove local resource management
