Subject: i2c: designware-platdrv: enable RuntimePM before registering to the core

From: Wolfram Sang <[email protected]>

commit 36d48fb5766aee9717e429f772046696b215282d upstream.

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.
