After exynos_dp have been split the common IP code into analogix_dp driver,
the analogix_dp driver have deprecated some Samsung platform properties which
could be dynamically parsed from EDID/MODE/DPCD message, so this is an update
for Exynos DTS file for dp-controller.

Beside the backward compatibility is fully preserved, so there are no
bisectability break that make this change in a separate patch.

Though the keyboard and other driver will continue to support the legacy
"gpio-key,wakeup", "linux-keypad,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 further copy-paste
duplication.

The kernel can use as the default console a serial port if is defined
as stdout device in the Device Tree.

This allows a board to be booted without the need of having a console
parameter in the kernel command line.

Currently the Spring DTS has bootargs in the /chosen node and this is
kept since users that don't have a serial console on this board might
be using it to have the boot log shown in the display. This will have
more precedence than the stdout-path but it's fine since is only used
when CONFIG_ARM_ATAG_DTB_COMPAT_CMDLINE_EXTEND is enabled.

exynos5250-cros-common.dtsi was meant for sharing common pieces across

was requested to be merged into the Snow device tree, sharing only the
keyboard controller for now. This may be re-evaluated as both mature.

key as CAPSLK.  However in all ChromeOS kernels it is L_META.  One can
certainly have long debates about which it ought to be, but I'm
proposing setting it to L_META because:
* That's how _all_ ChromeOS kernels do it and will do it.
* There is no L_META key on the board, so it's nice to have.
* For those people who really want it to be caps lock, they can use
  xmodmap or somesuch.
