usb: cdnsp: Add support for device-only configuration
This patch introduces support for operating the Cadence USBSSP (cdnsp)
controller in a peripheral-only mode, bypassing the Dual-Role Device (DRD)
logic.
The change in BAR indexing (from BAR 2 to BAR 1) is a direct
consequence of switching from 64-bit to 32-bit addressing in the
Peripheral-only configuration.
Tested on PCI platform with Device-only configuration. Platform-side
changes are included to support the PCI glue layer's property injection.
