Linus Walleij 8867258e70 dt-bindings: usb: Correct and extend FOTG210 schema
It turns out that this IP block exists in at least two
incarnations: FOTG200 and FOTG210. The one in the Gemini
is FOTG200, so add the variants and rectify the binding
for Gemini.

This affects things such as the placement of certain
registers.

It remains to be seen how similar this block is to the
third USB block from Faraday, FUSB220.
