Add the dwc2 bindings for the JZ4775 SoC, the JZ4780 SoC, the X1000 
SoC,
the X1600 SoC, the X1830 SoC, and the X2000 SoC from Ingenic.

I don't know if all these IPs are the exact same, but if they are, 
they all should have "ingenic,jz4775-otg" as the fallback.

I'm not too sure whether they are exactly the same, but comparing the 
code in Ingenics SDK,

the code of the USB part of jz4775, jz4780, and x1000 are the same, 
the code of the USB part

of x1600 and x1830 are the same, and the USB part code of X2000 are 
different from all of them.
In doubt - it's better to keep separate compatible strings, so this is 
OK.

Cheers,
-Paul
