This commit adds XUSB device mode controller support on Tegra234 SoC.
Tegra234 XUDC is very similar to the existing Tegra194 XUDC.

The device-tree binding documentation is missing for this compatible
string. Please send a patch to add this compatible string to the
appropriate binding doc.
Thanks. Sent out the change to add the compatible string to xudc binding
doc.

OK. Always best to send out these patches in a series together. I see Krzysztof asking for the driver and DTS change. Given that we are already at v6.0-rc7 this will not make v6.1, and so good to put all the patches together in a series and resend.

Thanks
Jon
