ARM: dts: mmp3: add Dell Wyse 3020 machine
This is a Dell Wyse thin client, variously referred to as "Ariel",
"3020" or "Tx0D" where "x" stands for the software it was shipped with.
I somewhat arbitrarily chose "ariel".
There are bits missing, because the drivers are not in and bindings are not
settled yet:
* Things missing from mmp3.dtsi:
HSIC controller and its PHY (only the internal Ethernet is connected
here, the hub with external USB2 ports is connected to the U2O controller
that works well), Vivante GC2000 GPU
* &twsi1/regulator@19
Marvell 88pm867 power regulator
* &twsi3/vga-dvi-encoder@76
Chrontel CH7033B-BF VGA & DVI encoder
* &twsi3/sound-codec@30
Sound chip, probably a Marvell 88ce156
* &twsi4/embedded-controller@58
ENE KB3930QF Embedded Controller, also seems to be connected to &ssp4.
Might not need a driver -- about the only useful thing it can do is to
reboot the machine when tickled via some GPIO lines.
Also there seems to be something at &twsi1 address 0x50.
