Currently, all imx pinctrl drivers maintain a big array of struct
imx_pin_reg which hard-codes data like register offset and mux mode
setting for each pin function. Every time a new imx SoC support is
added, we need to add such a big mount of data. With moving to single
kernel build, it's only matter of time to be blamed on memory consuming.
With DTC pre-processor support in place, the patch moves all these data
into device tree by redefining the PIN_FUNC_ID in imxXX-pinfunc.h and
changing the PIN_FUNC_ID parsing code a little bit.
The pin id gets re-numbered based on mux register offset, or config
register offset if the pin has no mux register, so that kernel can
identify the pin id from register offsets provided by device tree.
As a bonus point of the change, those arbitrary magic numbers standing
for particular PIN_FUNC_ID in device tree sources are now replaced by
macros to improve the readability of dts files.

Replace /include/ (dtc) with #include (C pre-processor) for all imx DT
files, so that gcc -E handles the entire include tree, and hence any of
those files can #include some other file e.g. for constant definitions.
This allows future use of #defines and header files in order to define
names for various constants, such as pinctrl settings. Use of those
features will increase the readability of the device tree files.

The keypad is on the accessory board of i.MX51 babbage
main board and is driven by Keypad Port(KPP) in SoC.
The keymap is the same to i.MX25 3stack platform as
the accessory board schematic tells that it is designed
in this way.

Following omap3-evm.dts way, it changes all imx dts files to use label
in board dts to refer to nodes defined by soc dtsi. Thus, the board
dts files become easier to read and edit with the least indentation
levels.

The babbage board has a DVI-I output which allows to output analog
and digital signals simultaneously. This patch adds support for it
to the devicetree. The DDC signals are not wired up on the board, so
DRM will fall back on default VESA modes.

Commit 88cde8b (ARM: dts: imx: update #interrupt-cells for gpio nodes)
changes gpio #interrupt-cells from 1 to 2 without updating the users.
It causes the gpio irq requesting call failing in client driver's probe
function.
Add the irq type cell for those gpio interrupt users to fix their
driver probe failure.
