Sync Linux kernel dwc3 changes from v4.15 to v4.16.
The following files are preserved accross the import:

dwc3-rtk.c dwc3-st.c dwc3-xilinx.c host.c trace.c trace.h ulpi.c
Note that this is a raw import and doesn't build.
A fixup commit at the end of the series fixes that.

Does this actually compile ? I don't think U-Boot code base contains
phy_calibrate() function ?
