Add legacy interrupt handler which would be more appropriate for
interrupt that is shared with other devices(e.g. USB) in system and
provide a new tunable "hw.msk.legacy_intr" to activate the legacy
interrupt handler. Setting the tunable automatically disables MSI
for msk(4). Previously msk(4) used adoptive polling with taskqueue(9)
as all msk(4) hardwares I know supports MSI. However, there are cases
that MSI couldn't be used on some hardwares due to bugs in MSI
implementatins.
