media: smiapp: Register sensor after enabling runtime PM on the device

[ Upstream commit 90c9e4a4dba9f4de331372e745fb1991c1faa598 ]

Earlier it was possible that the parts of the driver that assumed runtime
PM was enabled were being called before runtime PM was enabled in the
driver's probe function. So enable runtime PM before registering the
sub-device.
