The cm-fx6 module has an onboard Wolfson wm8731 codec which is muxed
to the ssi2 controller. Unlike most (all?) supported i.MX6 board/codec
combinations the wm8731 is operated in slave mode and the clock setup
is static.
Add support for it.

The license text has been mangled at some point then copy pasted across
multiple files. Restore it to what it should be.
Note that this is not intended as a license change.

Since commit b36581df7e ("spi: imx: Using existing properties for
chipselects") the device tree property 'fsl,spi-num-chipselects' is
unused and it is already marked as obsolete in device tree binding
documentation. Remove the property from the existing DTS files to
avoid its reoccurence on copying.

According to the schematics of CompuLab's sbc-fx6 baseboard and the
vendor devicetree GPIO_16 is *not* muxed to ENET_REF_CLK but to SPDIF_IN.
Remove the wrong pinctrl setting.

Several dts files set a bit in the SPEED field for pads
RGMII_{R,T}{XC,D0,D1,D2,D3,X_CTL}, but that doesn't exist. Writing there
doesn't have an effect and the bit reads as zero.

The current ldo settings of the cm-fx6 do not allow 1.2GHz cpu
frequency. At this frequency the module behaves unstable.
But the imx6q fuse indicates that 1.2GHz operation is possible.
Hence, remove the 1.2GHz operation point in the device tree.

GPLv2-only devicetrees make reuse difficult for software components
licensed under a different license. In particular, the Utilite Pro
devicetree file (which includes imx6q-cm-fx6.dts) is already dual
licensed under GPLv2/X11.
Hence, relicense imx6q-cm-fx6.dts under GPLv2/X11 dual license.

The cm-fx6 module has an on-board spi-flash chip for its firmware, an
eeprom (containing e.g. the mac address of the on-board Ethernet),
a sata port, a pcie controller, an USB hub, and an USB otg port.
Enable support for them. In addition, enable syscon poweroff support.

Add initial support for cm-fx6 module.
cm-fx6 is a module based on mx6q SoC with the following features:
- Up to 4GB of DDR3
- 1 LCD/DVI output port
- 1 HDMI output port
- 2 LVDS LCD ports
- Gigabit Ethernet
- Analog Audio
- CAN
- SATA
- NAND
- PCIE
This patch allows to boot up the module, configures the serial console,
the Ethernet adapter and the heartbeat led.
cm-fx6 is embedded inside the Utilite computer.
