It replaces the clk_register_clkdev in imx6q clock driver with DT
lookup. It depends on Mike's clk-3.7 branch.
When it gets merged together with imx-dt-3.7, there is a trivial
conflict on arch/arm/boot/dts/imx6q.dtsi.

Merge tag 'imx-clk-dt-lookup' into imx/dt-for-3.7-2
Conflicts:

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.

Change the indentation for property fsl,pins a little bit, so that
the first and the last line get the same indentation with all other
lines. Then it will be easier to copy and past any of these lines.

Some mxc processors have an edge_sel feature, which allows the IRQ to be
triggered by any edge.
This patch makes use of this feature if available, which skips mxc_flip_edge().

Imx6q sabrelite board uses ecspi1 to connect a spi flash sst25vf016b,
we need to add pinctrl information for it in the dts, otherwise the
ecspi1 driver can't work and the connected flash is wrongly
detected as a mr25h256 flash like this:
m25p80 spi32766.0: found mr25h256, expected sst25vf016b
