Now if the problem occurs that triggered the BUG_ON before, the machine
runs in a NULL pointer dereference.  So it wouldn't be much harder now
to debug the situation if it occured.

GPIO_INT_LOW_LEV is defined as

	(cpu_is_mx1_mx2() ? 0x3 : 0x0)

so depending on compiler optimisation and enabled SoCs this doesn't
qualify as a constant expression as needed by a switch statement.
Ditto for GPIO_INT_HIGH_LEV.

As the gpio ports have different addresses on imx21 and imx27 there are
two different port descriptions needed if not relying on the overloaded
cpp macro IO_ADDRESS.  So some cpp magic is added to minimize code
duplication.

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.

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
