media: imx355: Enable runtime PM before registering async sub-device

Browse source

commit efa5fe19c0 upstream.

As the sensor device maybe accessible right after its async sub-device is
registered, such as ipu-bridge will try to power up sensor by sensor's
client device's runtime PM from the async notifier callback, if runtime PM
is not enabled, it will fail.

So runtime PM should be ready before its async sub-device is registered
and accessible by others.
