Follow the recent trend for the license description, and also fix the
wrongly stated X11 to MIT.
As already pointed on the DT ML, the X11 license text [1] is explicitly
for the X Consortium and has a couple of extra clauses. The MIT
license text [2] is actually what the current DT files claim.

Control the Chromecast's two LEDs using PWM instead of GPIO pins. This
allows for variable brightness.

On the Chromecast, the bootloader provides us with an ATAG_MEM of
start=0x01000000 and size=0x3eff8000. This is clearly incorrect, as the
range given encompasses nearly a GiB but the Chromecast only has 512MiB
of RAM! Additionally, this causes the kernel to be decompressed at
0x00008000, below the claimed beginning of RAM, and so the boot fails.
Since the existing ATAG parsing code runs before the kernel is even
decompressed and irrevocably patches the device tree, don't even try
to bypass it. Instead, use the "linux,usable-memory" property instead
of the "reg" property to define the real range. The ATAG code only
overwrites reg, but linux,usable-memory is checked first in the OF
driver, so the fact that reg gets changed makes no difference.

Use stdout-path to specify the console and remove the console argument
from the kernel command line.

The current GPLv2 only licensing on this dts 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
this dts under a GPLv2/X11 dual-license.

This adds very basic device tree files for the Marvell Armada
1500-mini SoC (Berlin BG2CD) and the Google Chromecast. Currently,
SoC only has nodes for cpu, some clocks, l2 cache controller, local
timer, apb timers, uart, and interrupt controllers.
The Google Chromecast is a consumer device comprising the Armada
1500-mini SoC above.
