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.

This adds the stdout-path property to various i.MX boards. Values
of the property have been taken from barebox, so they should be
correct. Also, the older linux,stdout-path property is converted
to stdout-path.

This works around a hardware bug.
From "Chip Errata for the i.MX 6Dual/6Quad"
ERR006687 ENET: Only the ENET wake-up interrupt request can wake the
system from Wait mode.
The ENET block generates many interrupts. Only one of these interrupt lines
is connected to the General Power Controller (GPC) block, but a logical OR
of all of the ENET interrupts is connected to the General Interrupt Controller
(GIC). When the system enters Wait mode, a normal RX Done or TX Done does not
wake up the system because the GPC cannot see this interrupt. This impacts
performance of the ENET block because its interrupts are serviced only when
the chip exits Wait mode due to an interrupt from some other wake-up source.
Before this patch, ping times of a Sabre Lite board are quite
random:

Also, apply same change to imx6qdl-nitrogen6x.
This change may not be appropriate for all boards.
Sabre Lite uses GPIO6 as a power down output for a ov5642
camera. As this expansion board does not yet work with mainline,
this is not yet a conflict. It would be nice to have an alternative
fix for boards where this is a problem.
For example Sabre SD uses GPIO6 for I2C3_SDA. It also
has long ping times currently. But cannot use this fix
without giving up a touchscreen.
Its ping times are also random.

Explicitly sets the pad GPIO_0 (sys_mclk) to 0x030b0.
Before this patch, it has the value 0x130b0 if using mainline u-boot.
So this patch also removes hysteresis. The 100k pulldown remains so
that a disabled clock will be low.

This patch moves pin EIM_D23 (phy reset) from pinctrl_hog to pinctrl_enet.
It also explicitly sets the pad to 0x000b0.
Before this patch, it has the value 0x1b0b0 if using mainline u-boot.
So this patch also removes hysteresis and a 100K pullup since the pad
is always an output.

This makes the structure of Sabre Lite board files the same
as Sabre SD board files so that they are easier to compare.
By this, I mean that the majority of the file imx6q-sabrelite.dts
is moved to imx6qdl-sabrelite.dtsi so that both imx6q-sabrelite.dts
and imx6dl-sabrelite.dts can include it.
Now Sabre Lite has support for Dual Lite/Solo
processors.
