Subject: [PATCH] m68k: mcf5441x: create stub to use imx drivers

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.
