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.

This baseboard is used on the handbot and eybot robots.
The sel gpios are used as enables and rst signals on smartbot, thus the

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 SIC mask is only 2bits wide, not 4
- MX31_OTG_PM_BIT and MX31_H1_PM_BIT use negative logic
- clear MX31_H1_DT_BIT and MX31_H2_DT_BIT so that they can be cleared,
not only set.

Apart from MXC91231_IO_ADDRESS itself this was the only usage of
MXC91231_AIPS1_IO_ADDRESS. Now MXC91231_IO_ADDRESS can be recoded with
IMX_IO_ADDRESS and all helper macros can go away.

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
.
