media: i2c: ov01a10: Add power on/off sequencing support

So far the ov01a10 driver has only been used on laptops with an IVSC chip
where the IVSC chip controls the power on/off sequencing of the sensor.

But there are also designs with an ov01a10 sensor where the kernel needs
to directly take care of the power-sequencing, controlling clks, regulators
and GPIOs. Add support for these designs.

The 2 ms minimum reset assertion time is taken from other Omnivision sensor
drivers like the ov5675. The 20 ms delay after reset de-assert comes from
the out of tree ov01a1s driver.
