[PATCH v2 8/9] m68k: mcf5441x: create stub to use imx drivers

[Angelo Dureghello]

Some NXP imx hardware ip module as the esdhc controller are exactly the
same in some new ColdFire cpus. For the specific case, mcf5441x needs to
use the existing fsl_esdhc_imx.c driver for the esdhc device.

Create a stub to be able to use NXP "imx" serie drivers as the
fsl_esdhc_imx in the ColdFire architecture.
