pinctrl: imx: move hard-coding data into device tree
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.

kbuild: fixdep: support concatenated dep files
The current use-case for fixdep is: a source file is run through a single
processing step, which creates a single dependency file as a side-effect,
which fixdep transforms into the file used by the kernel build process.
In order to transparently run the C pre-processor on device-tree files,
we wish to run both gcc -E and dtc on a source file in a single rule.
This generates two dependency files, which must be transformed together
into the file used by the kernel build process. This change modifies
fixdep so it can process the concatenation of multiple separate input
dependency files, and produce a correct unified output.
The code changes have the slight benefit of transforming the loop in
parse_dep_file() into more of a lexer/tokenizer, with the loop body being
more of a parser. Previously, some of this logic was mixed together
before the loop. I also added some comments, which I hope are useful.
Benchmarking shows that on a cross-compiled ARM tegra_defconfig build,
there is less than 0.5 seconds speed decrease with this change, on top
of a build time of ~2m24s. This is probably within the noise.

kbuild: create an "include chroot" for DT bindings
The recent dtc+cpp support allows header files and C pre-processor
defines/macros to be used when compiling device tree files. These
headers will typically define various constants that are part of the
device tree bindings.
The original patch which set up the dtc+cpp include path only considered
using those headers from device tree files. However, most are also
useful for kernel code which needs to interpret the device tree.
In both the DT files and the kernel, I'd like to include the DT-related
headers in the same way, for example, <dt-bindings/gpio/tegra-gpio.h>.
That will simplify any text which discusses the DT header locations.
Creating a <dt-bindings/> for kernel source to use is as simple as
placing files into include/dt-bindings/.
However, when compiling DT files, the include path should be restricted
so that only the dt-bindings path is available; arbitrary kernel headers
shouldn't be exposed. For this reason, create a specific include
directory for use by dtc+cpp, and symlink dt-bindings from there to the
actual location of include/dt-bindings/. For want of a better location,
place this "include chroot" into the existing dts/ directory.
Some headers used by device tree files may not be useful to the kernel;
they may be used simply to aid in constructing the DT file (e.g. macros
to create a node), but not define any information that the kernel needs
to share. These may be placed directly into arch/*/boot/dts/ along with
the DT files themselves.
