media: i2c: max9286: [Workaround] Hard delay while waiting to enable the V3M cameras

The camera's power regulator is connected to a GPIO on the max9286.
Unfortunately this causes us a circular dependency on the regulator
needing the gpio_chip before the max9286 has probed.

Until we can get the regulator framework to create the regulator device
on demand (at the time of regulator_get(), the gpio_chip is available)
we need to force the gpio line with a gpio-hog, and handle the delay
required with a manual sleep.

This is specific to the Eagle-V3M.
