Subject: [PATCH v2 1/7] syscore: Pass context data to callbacks

From: Thierry Reding <treding@nvidia.com>

Pass a pointer to the syscore_ops structure that was registered to the
callbacks. This enables callbacks to act on instance data (syscore_ops
can be embedded into other structures, and driver-specific data can be
obtained using container_of()) rather than the current practice of
relying on global variables.

Changes in v2:
- add missing kerneldoc for added ops parameter
