Laurent Pinchart 7997196cb4 [media] mt9p031: Use bulk regulator API
The sensor is powered by three supplies. Use the bulk regulator API to
enable and disable them instead of performing the operations manually.
This fixes a warning caused by ignoring the return value of
regulator_enable().

This is no longer needed since the core now handles this through DBG_G_CHIP_INFO.

Guennadi Liakhovetski bbcc9fa0af [media] mt9p031: Power down the sensor if no supported device has been detected
The mt9p031 driver first accesses the I2C device in its .registered()
method. While doing that it first powers the device up, but if probing
fails, it doesn't power the chip back down. This patch fixes that bug.

Laurent Pinchart 97f212767a [media] mt9p031: Add support for regulators
Enable the regulators when powering the sensor up, and disable them when
powering it down.
The regulators are mandatory. Boards that don't allow controlling the
sensor power lines must provide fixed voltage regulators.
