usb: changes for v5.3 merge window

The biggest part here is a set of patches removing unnecesary variables
from several drivers.

Meson-g12a's dwc3 glue implemented IRQ-based OTG/DRD role swap.

Qcom's dwc3 glue added support for ACPI, mainly for the AArch64-based
SoCs.

DWC3 also got support for Intel Elkhart Lake platforms.
