fat: move fattime_mktime to timefuncs

This moves the time conversion function to timefuncs since it has
uses on ports that don't use the FAT driver. This function has no
dependency on the FAT driver as it is so this should not cause any
issues. To reflect this separation the function was renamed to
dostime_mktime since it is really for DOS timestamps. The places
where it was used have also been updated.
