Use of scan_static_bus() and tree traversals is somewhat convoluted.
Start cleaning this up by assigning each path type with separate
static scan_bus() function.
For ME, SMBus and LPC paths a bus cannot expose bridges, as those would
add to the number of encountered PCI buses.

As per discussion with lawyers[tm], it's not a good idea to
shorten the license header too much - not for legal reasons
but because there are tools that look for them, and giving
them a standard pattern simplifies things.
However, we got confirmation that we don't have to update
every file ever added to coreboot whenever the FSF gets a
new lease, but can drop the address instead.
util/kconfig is excluded because that's imported code that
we may want to synchronize every now and then.

This change switches all northbridge vendors and southbridges
to be autoincluded by Makefile.inc, rather than having to be
mentioned explicitly in northbridge/Makefile.inc or in
northbridge/<vendor>/Makefile.inc.
This means, vendor and northbridge directories are now "drop
in", e.g. be placed in the coreboot directory hierarchy
without having to modify any higher level coreboot files.
The long term plan is to enable out of tree components to be
built with a given coreboot version (given that the API did not
change).

Because we had no stack on romcc boards, we had a separate, not as
powerful clone of printk: print_*. Back in the day, like more than
half a decade ago, we migrated a lot of boards to printk, but we never
cleaned up the existing code to be consistent. instead, we worked around
the problem with a very messy console.h (nowadays the mess is hidden in
romstage_console.c and early_print.h)
This patch cleans up the northbridge code to use printk() on all non-ROMCC
boards.

Registered RAM is rarely used, so I suppose the code was never tested with them.
For unregistered RAM exactly the same codepath is followed.
