Subject: [PATCH] ARM: kirkwood: add missing <linux/if_ether.h> for ETH_ALEN

After commit 83216e3988cd1 ("of: net: pass the dst buffer to
of_get_mac_address()") build fails for kirkwood as ETH_ALEN is not
defined.

arch/arm/mach-mvebu/kirkwood.c: In function 'kirkwood_dt_eth_fixup':
arch/arm/mach-mvebu/kirkwood.c:87:13: error: 'ETH_ALEN' undeclared (first use in this function); did you mean 'ESTALE'?
   u8 tmpmac[ETH_ALEN];
             ^~~~~~~~
             ESTALE
arch/arm/mach-mvebu/kirkwood.c:87:13: note: each undeclared identifier is reported only once for each function it appears in
arch/arm/mach-mvebu/kirkwood.c:87:6: warning: unused variable 'tmpmac' [-Wunused-variable]
   u8 tmpmac[ETH_ALEN];
      ^~~~~~
make[5]: *** [scripts/Makefile.build:262: arch/arm/mach-mvebu/kirkwood.o] Error 1
make[5]: *** Waiting for unfinished jobs....

Add missing #include <linux/if_ether.h> to fix this.
