The CLKO is widely used by imx6q board designs to clock audio codec.
Since most codecs accept 24 MHz frequency, let's initially set up CLKO
with OSC24M (cko <-- cko2 <-- osc). Then those board specific CLKO
setup for audio codec can be removed.
The board dts files also need an update on cko reference in codec node.
ARM: dts: imx: remove old DMA binding data from gpmi node
After mxs-dma driver adopts generic DMA device tree binding, gpmi
channel interrupt number is defined in DMA controller node, and
channel ID is listed in "dmas" property. So the DMA channel interrupt
number in gpmi node "interrupts" property and fsl,gpmi-dma-channel which
are used by old customized DMA binding can be removed now.

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.

Commit 02502da45 (ASoC: imx-mc13783: Depend on ARCH_ARM) caused the selection of
CONFIG_SND_SOC_IMX_MC13783 to be impossible due to a wrong dependency, which
caused CONFIG_SND_SOC_IMX_MC13783 to be removed after the defconfigs cleanups.
The original selection problem has been fixed by 9f19de649f (ASoC: imx-mc13783:
Make SND_SOC_IMX_MC13783 visible again), so it is possible to select
CONFIG_SND_SOC_IMX_MC13783 again as originally done.
