[PATCH 3/4] i2c: s3c2410: enable RuntimePM before registering to the core

[Wolfram Sang]

From: Wolfram Sang <wsa+renesas@xxxxxxxxxxxxxxxxxxxx>

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.

Not tested on HW. Found by code review.
