Add option to log changes in USB 2.0 EHCI debug port connection.
For romstage move usbdebug as the last initialised console so one
actually can see these messages.
Init order of consoles in ramstage is undetermined and unchanged.

Store EHCI Debug Port runtime variables in CAR_GLOBAL.
For platforms without CAR_MIGRATION, logging on EHCI Debug Port is
temporarily lost when CAR is torn down at end of romstage.
On model_2065x and model_206ax ehci_debug_info was overlapping the MRC
variable region and additionally migration used incorrect size for
the structure.

There are other uses for EHCI debug port besides console, so move
EHCI relocation code from console to lib.

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.

Output to usbdebug console needs to be disabled until hardware is
initialized and while EHCI BAR is relocated. Add separate field
ehci_info to point to back to EHCI context when hardware is ready
to transfer data.

Some usb debug devices don't respond fast enough. The linux kernel
(which uses almost the same usbdebug code) added a bit more
retry code, so let's copy that. Even if it might look stupid,
i pass the DBG_LOOPS argument through all functions to keep
the code at least a bit in sync with the linux kernel code.

EHCI debug allows to send message with 8 bytes length, but
we're only sending one byte in each transaction. Buffer up
to 8 bytes to speed up debug output.

- move enable_usbdebug() declaration to usbdebug.h
- reinitialize debug driver in ramstage, as copying the data
structure from romstage doesn't work right now. This way of copying
data from romstage to ramstage is really board/cpu specific, and is
likely to break often. So don't do it.

- actually hook up usbdebug in printk/print_ for romstage
- make usbdebug.c more similar to the Linux kernel version it was
originally derived from.
- increase retries and timing for usbdebug init (at least one chipset
seems to need this)
- src/pc80/usbdebug_serial.c is not needed
- some small console cleanups

- Add missing license headers, or missing (C) lines to various files.
(most are from AMD / Yinghai Lu, based on svn logs)
- src/include/ehci.h was taken from the Linux kernel. Updating it to
the latest version from git HEAD while I'm at it (build-tested with
one board). It also sports some new EHCI 1.1 addendum #defines which
we may or may not need.
This new file also already has a proper GPL header.

The 'delay' variable shadows the global 'delay()' function, yielding
this compiler warning/error:
src/pc80/../lib/usbdebug.c: In function `ehci_reset_port':
src/pc80/../lib/usbdebug.c:281: error: declaration of `delay' shadows a global declaration
src/lib/delay.c:9: error: shadowed declaration is here
This fixes the issue by renaming the 'delay' variable to 'delay_ms'.

board porter: printk should always be available in CAR mode.
Also drop CONFIG_USE_INIT, it's only been selected on one ASROCK board
but it's not been used there. Very odd.
There is one usage of CONFIG_USE_INIT which was always off in
src/cpu/intel/car/cache_as_ram.inc and we have to figure out what to do with
those few lines.
