[ARM] 4887/1: i.MXC family: Separate current platform code
From: Juergen Beisert <j.beisert@pengutronix.de>
This patch separates the current code into i.MX2 and i.MX3 and modifies
the Kconfig files to reflect this separation in the menus.
Things happend since last review:
- make i.MX3 compile again
- fix some structure names to be conform with all the shared/common
sources from i.MX1/i.MX2
Previous changes:
- stay conform to other Kconfig files (note from Russell King)
