[PATCH v2 5/9] hw/net/e1000: Move macreg[] arrays to .rodata to save 1MiB of .data

["Philippe Mathieu-Daudé" <philmd@redhat.com>]

Each array consumes 256KiB of .data. As we do not reassign entries,
we can move it to the .rodata section, and save a total of 1MiB of
.data (size reported on x86_64 host).
