Subject: [PATCH 2/3] ARM: ux500: Add i2c configurations to the Device Tree
 for DB8500 based devices

Subject: [PATCH 2/3] ARM: ux500: Add i2c configurations to the Device Tree
 for DB8500 based devices

For correct operation of the i2c-nomadik driver, it requires some
information surrounding clock-frequencies, delay times and thresholds.
Here we apply those configurations to be used when a platform is
booted via the device Tree.
