Subject: [PATCH 18/18] ARM: dts: Add the FOTG210 USB host to Gemini boards

This adds the FOTG210 USB host controller to the Gemini
device trees. In the main SoC DTSI it is flagged as disabled
and then it is selectively enabled on the devices that utilize
it.

Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

ChangeLog v1->v2:
- Rebased to kernel v4.19-rc1
- Drop pinctrl-0 handle from the second USB port
- Add comment on how to deal with the USB pin control
