Splitting up options and files by subsystem

Back when I first started working on splitting up NOTES into MI and
MD sections, I brought up this idea and was met with mostly apathy.
The idea is to allow a subsystem (such as ACPI or a device driver used
on several platforms but not all, like atkbdc(4) and friends) to
specify its NOTES, files, and options contents into subsystem-specific
files that the architecture-specific files could then include.

For example, we could have a NOTES.acpi, options.acpi, and files.acpi
that were included by sys/{i386,ia64}/NOTES, options.{i386,ia64}, and
files.{i386,ia64}. Another example would be a NOTES.atkbdc,
files.atkbdc, and options.atkbdc for the atkbd(4), atkbdc(4), and psm(4)
drivers and related options.

IMO, this scales better than duplicating content across a bunch of
different files. Trying to get an Alpha LINT to successfully
config( Cool

is pointing out lots of places where our current model hasn't
scaled.
