Don't rely on the padctl settings established by the boot loader, but
explicitly specify the padctl values in DTB. This is also necessary to
be able to use the DTB files from the Linux kernel for future U-Boot
versions that support HW configuration via DTB.

It is not recommended to place the regulator nodes inside 'simple-bus',
so adjust them accordingly.

The motivation for rearranging this is to make it easier to add new
regulator nodes in the future.

The current GPL only licensing on the dts files makes it very
impractical for other software components licensed under another
license.

In order to make it easier for them to reuse our device trees,
relicense our dts files first under a GPL/X11 dual-license.

The FEC driver ignores the GPIO polarity from 'phy-reset-gpios' and
considers that the Ethernet PHY is active low, unless the
property 'phy-reset-active-high' is present.

Fix the device tree description by explicitly passing the
'GPIO_ACTIVE_LOW' flag to the 'phy-reset-gpios' property.

Since commit b36581df ("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.

As of commit 1006ed7e ("serial: imx: Use generic uart-has-rtscts
DT property"), the Freescale IMX UART driver recognizes the generic
"uart-has-rtscts" DT property, deprecating the vendor-specific
"fsl,uart-has-rtscts" DT property. Hence replace the latter by the
former in all DTS files.

Though the keyboard and other driver will continue to support the legacy
"gpio-key,wakeup", "linux,wakeup" and "enable-sdio-wakeup" boolean
property to enable the wakeup source, "wakeup-source" is the new
standard binding.

This patch replaces all the legacy wakeup properties with the unified
"wakeup-source" property in order to avoid any futher copy-paste
duplication.

cd-gpios polarity should be changed to GPIO_ACTIVE_LOW and wp-gpios
should be changed to GPIO_ACTIVE_HIGH.
Otherwise, the SD may not work properly due to wrong polarity inversion

The DAI mode is and should be configured by the sound card driver as
codec and ssi have to be in the right modes to communicate with each
other. It is possible to operate the ssi unit or the codec in master mode,
sometimes even on the same board in different configurations.

With the latest changes in the fsl-ssi driver, the 'fsl,mode' property
is only handled as a fallback property. If the sound card sets the DAI
mode correctly, this fallback configuration is dropped.

'enable-active-low' is not a valid property for a GPIO controlled regulator.

According to Documentation/devicetree/bindings/regulator/gpio-regulator.txt:

"Optional properties:
...
- enable-active-high	: Polarity of GPIO is active high (default is low)."

,so the correct way to define an active-low GPIO controlled regulator is to
simply not pass 'enable-active-high'.
