As the NFC controller has different addresses on imx21 and imx27 there
are two different devices needed if not relying on the overloaded cpp
macro NFC_BASE_ADDR.  So some cpp magic is added to minimize code
duplication.

As obviously these two defines need different names, the name of the old
device is #defined to the new one when building for only one of imx21 or
imx27.

There is only NFC_BASE_ADDR left which is defined differently for mx21
and mx27.

Apart from MXC91231_IO_ADDRESS itself this was the only usage of

The old names are defined only if the cpp symbol
IMX_NEEDS_DEPRECATED_SYMBOLS exists, which is defined (for now) for all
files below arch/arm/mach-mx1.

This was done earlier for mx2 and mx3, too.

USBD_INT0 is for now defined unconditionally to prevent breaking
drivers/usb/gadget/imx_udc.

While at it use IMX_IO_ADDRESS to define MX1_IO_ADDRESS which
adds a cast to the IO_ADDRESS macro fixing many warnings like

	arch/arm/mach-mx1/generic.c:51: warning: passing argument 1 of 'mxc_init_irq' makes pointer from integer without a cast

This include isn't needed and hurts when defining static inline
functions in mach/hardware.h (or files included by mach/hardware.h).

The reason is that the consumers of mach/uncompress.h are compiled using
-Dstatic= so the code for all inline function is included in e.g.
arch/arm/boot/compressed/misc.o.
