media: ov2740: Add regulator support
On some designs the regulators for the AVDD / DOVDD / DVDD power rails
are controlled by Linux.
Add support to the driver for getting regulators for these 3 rails and
for enabling these regulators when necessary.
The datasheet specifies a delay of 0ns between enabling the regulators,
IOW they can all 3 be enabled at the same time. This allows using the bulk
regulator API.
The regulator core will provide dummy regulators for the 3 power-rails
when necessary.
