[dif/usbdev] Decouple HW config from DIF handle init.

DIF libraries across most IPs have two DIFs for initializing and
configuring an IP (respectively):
1. `dif_<ip>_init(...)` initializes an IP DIF handle, and
2. `dif_<ip>_configure(...)` configures an IP with runtime parameters.

The usbdev DIF library did not conform to this pattern, rather it
combined the intended functionality of both DIFs above into the first
DIF listed above, the `dif_<ip>_init(...)` DIF.

This commit fixes this and enables the usbdev DIF library to conform to
the pattern used by most other DIF libraries, therefore making
auto-generation of IRQ integration-tests feasible.

About the project

OpenTitan is an open source silicon Root of Trust (RoT) project. OpenTitan will make the silicon RoT design and implementation more transparent, trustworthy, and secure for enterprises, platform providers, and chip manufacturers. OpenTitan is administered by lowRISC CIC as a collaborative project to produce high quality, open IP for instantiation as a full-featured product. See the OpenTitan site and OpenTitan docs for more information about the project.
