Configure the data and tag latency for the L2 cache. This improves the
system performance.

This configuration is taken from Freescale's kernel patch

"ENGR00153601 [MX6]Adjust L2 cache parameter" [1]

which does

writel(0x132, IO_ADDRESS(L2_BASE_ADDR + L2X0_TAG_LATENCY_CTRL));
writel(0x132, IO_ADDRESS(L2_BASE_ADDR + L2X0_DATA_LATENCY_CTRL));

In this patch we are doing the same via the device tree.

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.

While booting from device tree, imx6q used to provide twd clock lookup
by calling clk_register_clkdev() in clock driver.  However, the commit
bd603455 (ARM: use device tree to get smp_twd clock) forces DT boot to
look up the clock from device tree.  It causes the failure below when
twd driver tries to get the clock, and hence kernel has to calibrate the
local timer frequency.

 smp_twd: clock not found -2
 ...
 Calibrating local timer... 396.13MHz.

Fix the regression by providing twd clock lookup from device tree, and
remove the unused twd clk_register_clkdev() call from clock driver.

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.

Having labels before each node allows board bindings to reference
to nodes by using the &nodename {} notation. This way boards do not
have to resemble the whole devicetree layout. Due to less indention
needed the board files also get better readability. Since the label
make the documentation behind the nodes unnecessary it is removed.

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.
