eb4ded6925 ec/acpi: add mechanisms to clear EC output queue
EC's output could be considered as a queue, and sometimes (observed on
Thinkpad T400s during cold boot) a few (only one observed) garbage bytes
may detained in such queue after power up. Those garbage bytes should be
checked and discarded first before real interactions, otherwise they may
disrupt the interaction during EC's enablement, causing a locked rfkill.

a73b93157f tree: drop last paragraph of GPL copyright header
It encourages users from writing to the FSF without giving an address.
Linux also prefers to drop that and their checkpatch.pl (that we
imported) looks out for that.

This is the result of util/scripts/no-fsf-addresses.sh with no further
editing.

b890a1228d Remove address from GPLv2 headers
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.

b57fef9f3e src/ec: Sanitize headers and comment #endif pairings
Comment #endif /* FOO */ pairings.
Alphabetise headers and remove any #if CONFIG_ guards around them.

Background rational:
Remove guarding the inclusion of headers based on CONFIG_ options. This
*potentially* could hide issues such as functions being swapped from
under our feet, since different runtime behaviour could be declared with
the same function same name and type-signature. Hence, depending on the
header we happen to get may change runtime behaviour.

7592e8bd9c Add new ec subdir for Embedded Controllers and common ACPI EC support
Adds a new src/ec subdir for embedded controllers (mostly found in laptops)
and converts Getac P470 and Roda RK886EX to use the new ACPI EC instead
of having their own copies of those functions.
