Both of the aforementioned macros have been present in FreeBSD
for well over a decade: 2009 for `KOBJMETHOD_END`; 2011 for
`DEVMETHOD_END`.
Adapt all hardcoded references of `{0, 0}` with `DEVMETHOD_END`
and `KOBJMETHOD_END` as appropriate. This helps ensure that
future adaptations to drivers following patterns documented
in driver(9) can be made more easily/without issue.
