Add the DT property to all boards that have the hardware workaround
for erratum ERR006687 present. This allows the CPUidle driver to use
the deep idle states, even if the FEC is active.

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.

This is the usual large batch of DT updates. Lots and lots of smaller
changes, some of the larger ones to point out are:
- Rockchip veyron (Chromebook) support, as well as several other new boards
- DRM support on Atmel AT91SAM9N12EK
- USB additions on some Allwinner platforms
- Mediatek MT6580 support
- Freescale i.MX6UL support
- Cleanups for Renesas shmobile platforms
- Lots of added devices on LPC18xx
- Lots of added devices and boards on UniPhier
There's also some dependent code added here, in particular some branches
that are primarily merged through the clock tree.

Pull ARM DT updates from Olof Johansson:
"Ladies and gentlemen, we proudly announce to you the latest branch of
ARM device tree contents for the mainline kernel. Come and see, come
and see!
No less than twentythree thousand lines of additions! Just imagine the
joy you will have of using your mainline kernel on newly supported
hardware such as Rockchip Chromebooks, Freescale i.MX6UL boards or
UniPhier hardware!
For those of you feeling less adventurous, added hardware support on
platforms such as TI DM814x and Gumstix Overo platforms might be more
of your liking.
We've got something for everyone here!
Ahem. Cough. So, anyway...

Currently it is not possible to have HDMI and LVDS working simultaneously,
because both ports try to use PLL5.
Move the LVDS clock parent to PLL3_USB_OTG, so that HDMI and LVDS can be
driven from independent sources.
With this change the LDB pixel clock goes to 68.57 MHz, which is still
within the valid range for the HSD100PXN1 LVDS panel.

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 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.

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.
