A 32-bit long storing microseconds will rollover every ~1.19 hours.
This can cause stopwatch to misbehave, causing unexpected failures.
If the current field in stopwatch is near 2^31, the expires field may
rollover when initialized. If this occurs, stopwatch_expired() will
instantly return true.
If current and expires fields are near 2^31, the current field could
rollover before being checked. In this case, stopwatch_expired() will
not return true for over an hour. Also stopwatch_duration_usecs() will
return a large negative duration.
This issue has only been observed in SMM since it never takes more
than 35 minutes to boot.
Switching to uint64_t mitigates this issue since it will not rollover
for over 500K+ years. The raw TSC would rollover sooner than this,
~200 years, depending on the tick frequency.

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.

A very common pattern in drivers is that we need to wait for a condition
to become true (e.g. for a lock bit in a PLL status register to become
set), but we still want to have a maximum timeout before we treat it as
an error. coreboot uses the stopwatch API for this, but it's still a
little verbose for the most simple cases. This patch introduces two new
helper macros that wrap this common application of the stopwatch API in
a single line: wait_ms(XXX, YYY) waits for up to XXX milliseconds to see
if the C condition 'if (YYY)' becomes true. The return value is 0 on
failure (i.e. timeout expires without the condition becoming true) and
the amount of elapsed time on success, so it can be used both in a
boolean context and to log the amount of time waited.
Replace the custom version used in an MTK ADC driver with this new
generic version.

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.

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.

The current way to get a simple mono_time difference is:
1. Declare a rela_time struct
2. Assign it the value of mono_time_diff(t1, t2)
3. Get microseconds from it using rela_time_in_microseconds().
This patch adds a simpler method. Now one only needs to call
mono_time_diff_microseconds(t1, t2) to obtain the same value which
is produced from the above three steps.

The notion of a monotonic timer is introduced. Along with it
are helper functions and other types for comparing times. This
is just the framework where it is the responsibility of the
chipset/board to provide the implementation of timer_monotonic_get().
The reason structs are used instead of native types is to allow
for future changes to the data structure without chaning all the
call sites.
