i2c: s3c2410: enable RuntimePM before registering to the core
[ Upstream commit eadd709f5d2e8aebb1b7bf49460e97a68d81a9b0 ]
The core may register clients attached to this master which may use
funtionality from the master. So, RuntimePM must be enabled before, otherwise
this will fail. While here, move drvdata, too.
