driver/memory:Move Freescale IFC driver to a common driver
Freescale IFC controller has been used for mpc8xxx. It will be used for ARM-based SoC as well. This patch moves the driver to driver/memory and fix the header file includes. Also remove module_platform_driver() and instead call platform_driver_register() from subsys_initcall() to make sure this module has been loaded before MTD partition parsing starts.
