From: Magnus Damm <damm@xxxxxxxxxx>
This patch reworks platform driver power management code
for i2c-s3c2410 from legacy callbacks to dev_pm_ops.
The callbacks are converted for CONFIG_SUSPEND like this:
suspend_late() -> suspend_noirq()
resume() -> resume()
Signed-off-by: Magnus Damm <damm@xxxxxxxxxx>

Untested but compiles fine.
