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.
- return -EINVAL if called with an invalid controller number

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

.

	arch/arm/kernel/debug.S:163: Error: constant expression expected -- `ldrne r3,=(((UART1_BASE_ADDR)-AIPI_BASE_ADDR)+AIPI_BASE_ADDR_VIRT)'

when compiling for mx2 with CONFIG_DEBUG_LL=y.  A similar error exists
on mx3 and is fixed by this commit, too.

This has the addional effect that the macros CSCR_U, CSCR_L and CSCR_A
are not used anymore in mach-pcm038.c and mach-qong.c.  These still use
the deprecated IO_ADDRESS macro and shouldn't be used in new code.
