Instead of adding the support of regulators in each device, let's think about
whether it is possible to create a global regulator for any device on the I2C bus.

I see it like this:
We add an extra field in the i2c_board_info structure "power_name" and handle
it in the i2c_device_{probe/remove} functions.

This would need to be an array of supplies, relatively few devices need
only a single power supply.  This is also not something that should be
handled in I2C, power is not something that's uniquely needed by devices
on an I2C bus.

Additional regulators can be handled in the driver, or "parent"-scheme can
be used. Is not it?
