Fix MAC address for Realtek 8110S based NAS

[Frank Wille <frank%phoenix.owl.de@localhost>]

Hi!

On Christmas I fixed altboot(8) to read the correct MAC address from
the flash ROM of a QNAP V200 board (tested with TS-100 and TS-101):

All re(4) based sandpoint NAS lack the EEPROM to store the MAC address.
For QNAP V200 it is stored in an ext2 file system (ETH0.MAC_ADDR) of
the Flash ROM. For NH230/231 based NAS we can rely on UBoot to configure
the chip's IDR register correctly.

Unfortunately in all cases you also have to patch sys/dev/ic/rtl8169.c,
because re(4) always wants to read the MAC address from the EEPROM,
which is wrong (IMHO)!

The following simple patch fixes that (not committed, because I have
to discuss that with the author first):
