usbdebug: Move ehci_debug_info allocation

Move ehci_debug_info allocation from console to lib, as console code
was only built for ramstage.

Implement dbgp_ehci_info() to return the EHCI context. Alread alias this
as dbgp_console_input() and _output() to return the console stream context
later on.
