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.

All currently supported i.MX25-based machines use phy_type = "utmi" and
dr_mode = "otg".  So this seems to be a sensible default.

This also doesn't hurt out-of-tree machines because up to now they had
to specify these two properties in the machine.dts which still takes
precedence by just overwriting the defaults added here.

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.

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
specified in DT after switch to common parsing function mmc_of_parse().

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.

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.
