This change updates the align attribute of memranges to be represented
as log2 of the required alignment. This makes it consistent with how
alignment is stored in struct resource as well.
Additionally, since memranges only allow power of 2 alignments, this
change allows getting rid of checks at runtime and hence failure cases
for non-power of 2 alignments.
This change also updates the type of align to be unsigned char.

They're listed in AUTHORS and often incorrect anyway, for example:
- What's a "Copyright $year-present"?
- Which incarnation of Google (Inc, LLC, ...) is the current
copyright holder?
- People sometimes have their editor auto-add themselves to files even
though they only deleted stuff
- Or they let the editor automatically update the copyright year,
because why not?
- Who is the copyright holder "The coreboot project Authors"?
- Or "Generated Code"?
Sidestep all these issues by simply not putting these notices in
individual files, let's list all copyright holders in AUTHORS instead
and use the git history to deal with the rest.

This change adds a helper function memranges_is_empty() which returns

This change adds memranges_steal() which allows the user
to steal memory from the list of available ranges by providing a set
of constraints (limit, size, alignment, tag). It tries to find the
first big enough range that can satisfy the constraints, creates a
hole as per the request and returns base of the stolen memory.

This change enables memranges library to support addresses with
different alignments. Before this change, memranges library supported
aligning addresses to 4KiB only. Though this works for most cases, it
might not be the right alignment for every use case. Example: There
are some resource allocator changes coming up that require a different
alignment when handling the range list.
This change adds a align parameter to struct memranges that determines
the alignment of all range lists in that memrange. In order to
continue supporting current users of memranges, default alignment is
maintained as 4KiB.

Instead of solely relying on malloc for building up an address space
for the range_entry objects allow one to supply a list of free entries
to memranges_init_empty(). Doing this and only calling malloc() in
ramstage allows a memranges oboject to be used in a malloc()-free
environment.

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.

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.

Be more conservative and only add VGA devices' prefetchable
resources as write-combining in the address space. Previously
all prefetchable memory was added as a write-combining memory
type. Some hardware incorrectly advertises its BAR as
prefetchable when it shouldn't be.
A new memranges_add_resources_filter() function is added
to provide additional filtering on device and resource.

The memranges_update_tag() function replaces all instances
that are tagged with old_tag and update to new_tag. This
can be helpful in the MTRR code by adjusting the address
space if certain memory types cause the MTRR usage to
become too large.

Two convenience functions are added to operate on a range_entry:
- range_entry_update_tag() - update the entry's tag
- memranges_next_entry() - get the next entry after the one provide
These functions will be used by a follow on patch to the MTRR code
to allow hole punching in WB region when the default MTRR type is
UC.

The memrange infrastructure allows for keeping track of the
machine's physical address space. Each memory_range entry in
a memory_ranges structure can be tagged with an arbitrary value.
It supports merging and deleting ranges as well as filling in
holes in the address space with a particular tag.
The memrange infrastructure will serve as a shared implementation
for address tracking by the MTRR and coreboot mem table code.
