This is still broken on 5250:
http://arm-soc.lixom.net/bootlogs/misc/v3.16-10143-gccefc7a/ is with
this patch applied on top of current mainline and the few fixes we
have queued up.

I2C_S3C2410 is enabled with that config now.

Tushar is no longer on a Linaro landing team, so he's not looking
after Arndale. Kukjin?
