net: dec: tulip: de2104x: Add shutdown handler to stop NIC
The driver does not implement a shutdown handler which leads to issues
when using kexec in certain scenarios. The NIC keeps on fetching
descriptors which gets flagged by the IOMMU with errors like this:
DMAR: DMAR:[DMA read] Request device [5e:00.0]fault addr fffff000
DMAR: DMAR:[DMA read] Request device [5e:00.0]fault addr fffff000
DMAR: DMAR:[DMA read] Request device [5e:00.0]fault addr fffff000
