This breaks non-DT users of this driver.  The device in arch/arm/mach-kirkwood
is left as "kirkwood-i2s" but the platform device is now called something
different.

You've only just introduced "marvell,kirkwood-i2s" in the previous patch.
Why introduce something and then immediately change its name?  This makes
no sense what so ever.
