gemini: Use library functions to assign MAC address
This simplifies the ethernet address extraction script by using standard library functions to locate the MTD partitions and extract ethernet address from a binary offset location in the flash. Furthermore, the aging ifconfig is replaced by the ip tool, which will now assign the MAC addresses. Suggested-by: Christian Lamparter <chunkeey@gmail.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Christian Lamparter <chunkeey@gmail.com> [ifconfig replacement, use -n instead of ! -z, -n requires string to be quoted within the test brackets, drop prepended "x" in check, add quotes, make local variables local, kill whitespaces] (cherry picked from commit cd6c3535cd2c7779a8d65f792c36082ee3822c11)
