media: i2c: imx219: Rectify runtime PM handling in probe and remove

commit 42eceae9 upstream.

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.

Also set the device's runtime PM status to suspended in remove only if it
wasn't so already.
