Yep, all veyriants use uart 2, even when they're not chromebooks.
Feel free to put it in the other file instead.

Otherwise it'll make things like the Asus Chromebit (mickey), AOpen
Chromebox mini (fievel), and AOpen Chromebase (tiger) unhappy
while debugging.

The rk3288-veyron-chromebook.dtsi file is more for things that make
a chromebook portable. Ex: built in display, lid switch, cros-ec.

Note how we have no uart2 references either in our tree in the
chromebook specific dtsi:
