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.

-Integrated Flash Controller
-
-Properties:
-- name : Should be ifc
-- compatible : should contain "fsl,ifc". The version of the integrated
- flash controller can be found in the IFC_REV register at
- offset zero.
-
-- #address-cells : Should be either two or three. The first cell is the
- chipselect number, and the remaining cells are the
- offset into the chipselect.
-- #size-cells : Either one or two, depending on how large each chipselect
- can be.
-- reg : Offset and length of the register set for the device
-- interrupts: IFC may have one or two interrupts. If two interrupt
- specifiers are present, the first is the "common"
- interrupt (CM_EVTER_STAT), and the second is the NAND
- interrupt (NAND_EVTER_STAT). If there is only one,
- that interrupt reports both types of event.
-
-
-- ranges : Each range corresponds to a single chipselect, and covers
- the entire access window as configured.
-
-Child device nodes describe the devices connected to IFC such as NOR (e.g.
-cfi-flash) and NAND (fsl,ifc-nand). There might be board specific devices
-like FPGAs, CPLDs, etc.
-
-Example:
-
- ifc@ffe1e000 {
- compatible = "fsl,ifc", "simple-bus";
- #address-cells = <2>;
- #size-cells = <1>;
- reg = <0x0 0xffe1e000 0 0x2000>;
- interrupts = <16 2 19 2>;
-
- /* NOR, NAND Flashes and CPLD on board */
- ranges = <0x0 0x0 0x0 0xee000000 0x02000000
- 0x1 0x0 0x0 0xffa00000 0x00010000
