After discussions with Nate, repo copy the acpi assist drivers from

Browse source 
i386 to dev/acpi_support.  In theory, these devices could be found
other than in i386 machines only as amd64 becomes more popular.  These
drivers don't appear to do anything i386 specific, so move them to
dev/acpi_support.  Move config lines to files so that those
architectures that don't support kernel modules can build them into
the kernel.  At the same time, rename acpi_snc to acpi_sony to follow
the lead of all the other specialty devices.
