usbdebug: Split PCI EHCI part There are EHCI compatible host controllers on ARM without PCI bus architecture. Currently we have not come across one with the debug capability though.

usbdebug: Unify console API Struct dbgp_pipe would not be suitable for use with xHCI. Just use an index, it is easy to setup in Kconfig if our future debug setup has separate pipes for console output and debugging/traceings.
