The commit also introduces the HAVE_FB_IMX config that is to be selected from
the MX25 platform config. Once this commit gets merged, the two other i.MX
archs, ARCH_MX1 and ARCH_MX2, should follow this one.

We noticed that we were only able to communicate once with a GSM module
per session, if we powered down the module then the serial driver was
broken until reset, no traffic or /proc/interrupts activity could be
seen any more.

Volker noticed it was provoked by a long "break" seen on the wire when
the RX was not driven during powerdown, we discovered we could kill the
serial driver just by forcing RX low extenally for a little while.

I saw that the processing for BREAK in the driver gets too excited and
clears down all set bits in USR2, including that a character is pending.
This stops all further characters getting processed.

The attached one-liner makes the serial driver immortal against BREAK.

Refactor the timer code into version 1 and version 2.

Essentially there are 2 versions of the timer hardware on Freescale MXC
hardware. Version 1 is found on MX1/MXL, MX21 and MX27. Version 2 is found on
MX25, MX31, MX35, MX37, MX51, and future parts.

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
