[PATCHv3 3/8] i2c: omap: remove the dtrev

[Shubhrajyoti D <shubhrajyoti-l0cyMroinI0@public.gmane.org>]

The dtrev is used only for the comments. Remove the same and use
the scheme instead to know if it is version2.

Signed-off-by: Shubhrajyoti D <shubhrajyoti-l0cyMroinI0@public.gmane.org>
---
v3: remove the scheme from the commments.
todo: remove the dtrev from hwmod etc.
