usb: changes for v4.19

Not a big pull request with only 37 non-merge commits, most of which
are touching dwc2 (74% of the changes).

The most important changes are dwc2's support for uframe scheduling
and its endian-agnostic readl/writel wrappers.

From dwc3 side we have a special new glue layer for Synopsys HAPS
which will help Synopsys running FPGA validation using our upstream
driver. We also have the beginnings of dual-role support for Intel
Merrifield platform.

Apart from these, just a series of non-critical changes.
