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.

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

USB device end toggles data PID when we ACK'd the zero-length data
packet. As USB host we need to toggle data PID too or the next data
received would get discarded.

Also relocate and split header files, there is some interest
for EHCI debug support without PCI.
