[PATCH 1/2] media: ov5645: Remove unneeded regulator_set_voltage()

[Fabio Estevam]

There is no need to call regulator_set_voltage() for each regulator
that powers the camera.

The voltage value for each regulator should be retrieved from the
device tree, so remove the unneeded regulator_set_voltage().
