3-stack is a reference board from Freescale for their i.MX51 SoC.

Add board definition, Kconfig and Makefile to enable Freescale 3-stack
board.

Boot tested on a i.MX51 3-stack Rev2.0 board

Because we add a 3ds debug board support in mxc level, we remove

The debug board is little different for all mxc 3-stack(PDK)
platforms, it is possible here to add a common implementation to
support this board.

These GPIO bank offsets are useful when define a gpio number.
E.G. when GPIO PORTC pin 6 is used for irq request pin of external
expanding device, we can define it like:
  #define EXP_PARENT_IRQ_PIN (GPIO_PORTC + 6)
