Only imx6q has the ahci sata controller, enable
it on imx6q platforms.

Shawn Guo c56009b2f6 ARM: dts: imx: share pad macro names between imx6q and imx6dl
The imx6q and imx6dl are two pin-to-pin compatible SoCs.  The same board
design can work with either chip plugged into the socket, e.g. sabresd
and sabreauto boards.

We currently define pin groups in imx6q.dtsi and imx6dl.dtsi
respectively because the pad macro names are different between two
chips.  This brings a maintenance burden on having the same label point
to the same pin group defined in two places.

The patch replaces prefix MX6Q_ and MX6DL_ with MX6QDL_ for both SoCs
pad macro names.  Then the pin groups becomes completely common between
imx6q and imx6dl and can just be moved into imx6qdl.dtsi, so that the
long term maintenance of imx6q/dt pin settings becomes easier.

Unfortunately, the change brings some dramatic diff stat, but it's all
about DTS file, and the ultimate net diff stat is good.

Shawn Guo 082d33d08f ARM: dts: imx: make sabreauto and sabresd common
The sabreauto and sabresd boards are common for imx6q and imx6dl.
Create imx6qdl-sabreauto.dtsi and imx6qdl-sabresd.dtsi for those
common parts.

Shawn Guo e16415313c 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.

Shawn Guo 36dffd8f49 ARM: imx: use #include for all device trees
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.

Shawn Guo 7c1da5854f ARM: dts: add dtsi for imx6q and imx6dl
Add dtsi for imx6q and imx6dl with non-common blocks moved into there.
Major differences between imx6dl and imx6q:

 * Dual vs. Quad cores
 * single vs. dual IPU
 * 128 vs. 256 KB OCRAM
 * imx6q: ECSPI5, OpenVG (GC355), SATA
 * imx6dl: I2C4, PXP, EPDC, LCDIF
 * iomuxc/pads definition

Shawn Guo 4bacf2a3fc ARM: dts: rename imx6q.dtsi to imx6qdl.dtsi
i.MX6 Quad and i.MX6 DualLite is similar enough to share one dtsi
file, so rename imx6q.dtsi to imx6qdl.dtsi preparing for the addition
of imx6dl support.

Another member of i.MX6 series i.MX6 SoloLite is different enough
from the other two, so it will stand as a separate dtsi.  That's why
we rename to imx6qdl.dtsi not imx6.dtsi.

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.
