USB: changes for v5.5

We have TI's glue layer for the Cadence USB3 controller going
upstream. Tegra's XUDC driver is also going upstream with this pull
request.

Apart from these two big features, we have a bunch of patches switching
over to devm_platform_ioremap_resource() in order to simplify code a
little; and a non-critical fix for DWC3 usage via kexec.
