usb_controller_initialize() is not declared in any header file nor
called from outside of usbinit.c, so make it static.
set_configuration() looks like beeing non-static on purpose (like the
other helpers around it in usb.c), so put a prototype into usb.h.

While it might be slightly more convenient to not have to call usb_poll
manually after calling usb_initialize, you'll still likely want to call it
before trying to use a USB device since one have have been hotplugged since
you last looked. By not calling usb_poll, usb_initialize completes quickly and
can be called unconditionally without a long delay. The delay can be put off
until later when we're sure it's necessary.

The usb_initialize function would scan for USB host controllers by brute force
iterating over all possible busses, devices, and functions. This change makes
it recursively scan busses only if it finds them on the other side of a bridge,
and only scan for functions beyond function 0 if the device claims to be
multifunction.
This change also takes the opportunity to clean up some style problems
throughout the file.

So far it was empty and never published. It now exists and shuts down
all controllers (esp. EHCI which resets the port routers).

The USB stack is pretty noisy. Reduce the output to a sane level.

The Intel E6XX Atom processor reports an unknown USB controller type (in
addition to the standard EHCI and OHCI ones). Add a default case to
print a warning when an unknown controller type is detected.

Interrupt transfer support is missing (ie. no keyboard),
bulk and control transfers work (ie. mass storage).

and 5. They're not found if only function 0 is checked. So if a device
exists at all, try all its functions. usb_controller_initialize() will
silently skip all device classes != 0C03.

Improve scanning for USB controllers.
Limitations:
- OHCI doesn't support interrupt transfers yet (ie. no keyboards)
- xHCI just does initialization and device attach/detach so far

Rename the generated config file to libpayload-config.h to differenciate
it from other config.h files. Move the default location of the file to
$(src)/include so that LIBPAYLOAD_PREFIX= users can access the file
without staging it.

memalign implementation (eg. the one I sent yesterday).
Features:
- UHCI controller driver
- UHCI root hub driver
- USB MSC (Mass Storage Class) driver
- skeleton of a USB HID driver
(requires better interrupt transfer handling, which is TODO)
- skeleton of a USB hub driver
(needs several blank spots filled in, eg. power management.
Again: TODO)
OHCI and EHCI are not supported, though OHCI support should be rather
easy as the stack provides reasonable abstractions (or so I hope). EHCI
will probably be more complicated.
Isochronous transfers (eg. webcams, audio stuff, ...) are not supported.
They can be, but I doubt we'll have a reason for that in the boot
environment.
The MSC driver was tested against a couple of USB flash drives, and
should be reasonably tolerant by now. But I probably underestimate
the amount of bugs present in USB flash drives, so feedback is welcome.
