Armada8K has one simple register for unit soft reset, which is part of
the system controller register area. The simple reset code doesn't
support register access via regmap for the syscon devices. This patch
series created a new driver based on the simple reset code, and add
Armada8K support then.

Thanks,
Wilson

Changes in v3:
  - Abandoned the use of the 'offset' property to specify the register
    offset.
  - Dropped the changes to 'cp110-system-controller.txt'.
  - Created a new dt-binding head file to define the reset lines.
  - Fixed the errors and warnings reported by dt_binding_check and
    dtbs_check.

Changes in v2:
  - Created a new driver for SYSCON device instead of extending the
    simple reset code.
  - Allow to retreive the register offset from the 'reg' property as
    an alternative to the 'offset' property.
  - Allow to retrevie the register size from the 'reg' property to
    calculate the number of reset lines.
  - Added the new dt-binding files to document the device-tree scheme
    and fix DT check issues.
  - Updated the device-tree node name to 'reset-controller' to follow
    the name conventions.

Changes in v1:
  - Init version.
