Subject: [PATCH 2/2] MIPS: RB532: Avoid undefined mac_pton without GENERIC_NET_UTILS

Currently MIPS allnoconfig with CONFIG_MIKROTIK_RB532=y fails to link
due to missing support for mac_pton():

  LD      vmlinux
arch/mips/rb532/devices.o: In function `setup_kmac':
devices.c:(.init.text+0xc): undefined reference to `mac_pton'

Rather than adding dependencies to the platform to force inclusion of
GENERIC_NET_UTILS which is selected by CONFIG_NET, just exclude the
setup of the MAC address if CONFIG_NET is not selected in the kernel
config.
