NET_DSA_MV88E6060 has already been used for this device (tl-wr941nd v2/
v3) in ar71xx, using platform data 


https://git.openwrt.org/?p=openwrt/openwrt.git;a=blob;f=target/linux/ar71xx/files/arch/mips/ath79/mach-tl-wr941nd.c;hb=refs/heads/openwrt-19.07
https://git.openwrt.org/?p=openwrt/openwrt.git;a=blob;f=target/linux/ar71xx/config-4.14;h=9a524fae4316caa10431bd6b3b4dadbe8660f14c;hb=refs/heads/openwrt-19.07#l433
https://git.openwrt.org/?p=openwrt/openwrt.git;a=blob;f=target/linux/ar71xx/base-files/etc/board.d/02_network;h=44fce970c0fd8b4811242fac0b53764a09244a2f;hb=refs/heads/openwrt-19.07#l324

so it should be possible for ath25 as well, although the effort might
not be worth it, considering the age and specifications of the target
devices.
