media: i2c: ov08d10: fix runtime PM handling in probe

Set the device's runtime PM status and enable runtime PM before registering
the async sub-device. This is needed to avoid the case where the device is
runtime PM resumed while runtime PM has not been enabled yet.

Remove the related, non-driver-specific comment while at it.
