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

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.

Continued device tree conversion and enablement across a number of
platforms; Kirkwood, tegra, i.MX, Exynos, zynq and a couple of other
smaller series as well.
ux500 has seen continued conversion for platforms. Several platforms have
seen pinctrl-via-devicetree conversions for simpler multiplatform. Tegra
is adding data for new devices/drivers, and Exynos has a bunch of new
bindings and devices added as well.
So, pretty much the same progression in the right direction as the last
few releases.

This is some amount of work left/forgot from device tree conversion.
Instead of checking cpu_is_xxx to determine the controller type, the
driver should use platform_device_id, which should match the device
tree compatible string.
The patch changes the driver to use platform_device_id rather than
cpu_is_xxx to determine the controller type/version. It also updates
the platform code and device tree source accordingly.
As the result, mach/hardware.h inclusion gets removed from the driver.

It really becomes an maintenance issue that every time a device needs
to look up (clk_get) a clock we have to patch kernel clock file to call
clk_register_clkdev for that clock.
Since clock DT support which is meant to resolve clock lookup in device
tree is in place, the patch moves imx6q client devices' clock lookup
over to device tree, so that any new lookup to be added at later time
can just get done in DT instead of kernel.

Add support for the new smp_twd runtime registration interface
to the imx6q platforms, and remove the old compile-time support.
The imx6q DTS file is updated to match the TWD DT documentation.
Also present in this patch a DTS fix to the timer interrupt routing
(the PPI connection uses bits [15:8]) and trigger (rising edge).
