This patch takes the black level value for the given sensor from its
specification, if available.  The initial intention was to get the value
from the tuning file but in the meantime the value was added to
CameraSensorHelper so it’s taken from there.

Changes in v5:
- Added a patch to take black level from the tuning file.

Changes in v4:
- Added braces around a single-line ‘if’ with a comment.

Changes in v3:
- A clarifying comment about the bit widths added.

Changes in v2:
- Rebased on the merged version of software ISP refactoring.
- The black level is represented as a pixel value rather than a 0..1
  floating value.
