platform/x86: int3472: For mt9m114 sensors map powerdown to powerenable
mt9m114 atomisp designs declare both reset and powerdown pins in their
GPIO type DSM, but the mt9m114 only has a reset pin. The powerdown pin
seems to control the regulators suppyling power to the sensor and
the privacy LED.
Add a mapping of powerdown to powerenable for the mt9m114 for this.
While at is also add a comment to document the ov7251 mapping.
