This allows the use of either or both declarations from
the files mx6q_pins.h and mx6dl_pins.h.

All board files should include <asm/arch/mx6-pins.h>
with one of the following defined in boards.cfg
    MX6Q   - for boards targeting i.MX6Q or i.MX6D
    MX6DL  - for boards targeting i.MX6DL
    MX6S   - for boards targeting i.MX6S
    MX6QDL - for boards that support any of the above with
             run-time detection

Pad declarations will be MX6_PAD_x for single-variant boards
and MX6Q_PAD_x and MX6DL_PAD_x for boards supporting both
processor classes.

Since the titanium board is not a Freescale board, move its
BSP code from the freescale board directory to the newly created
barco board directory.

PUE requires PKE to mean something, as do pull values with PUE, so do not
compell users to explicitly use PKE and PUE everywhere. This is also what is
done on Linux and what has already been done for i.MX51.

By the way, remove some unused pad control definitions.

There is no change of behavior.

Note that SPI_PAD_CTRL was defined by several boards with a pull value, but
without PKE or PUE, which means that no pull was actually enabled in the pad.
This might be a bug in those boards, but this patch does not change the
behavior, so it just removes the meaningless pull value from those definitions.

Titanium is a i.MX6 based board from ProjectionDesign / Barco. This
patch adds support for this board with the newly introduced NAND
support for i.MX6.
