Detailed Description

USB FS / HS register window (device-mode subset).

Modelled after the FSP/CMSIS R_USB_FS0_Type and R_USB_HS0_Type register layouts, restricted to the offsets the device-mode driver actually touches. Trailing HS-only registers (PHYSET, LPCTRL, LPSTS, BCCTRL, ...) are intentionally omitted; the driver does not enable HS-PHY power-down sequences yet.
