[PATCH] fff-network: apply upstream swap of MAC addresses for Archer C60

The ethernet MAC addresses of the Archer C60 v1/v2 were swapped
compared to the vendor assignment. This has been fixed in OpenWrt
after 19.07.2.
Apply this to our firmware already, so we cannot forget it later
and prevent having messed-up br-mesh MAC addresses.
The OpenWrt patches can be removed again when bumping to 19.07.3.

This can only be applied after changing to 19.07.2!

+Subject: ar71xx: fix swapped LAN/WAN MAC address for Archer C60 v1/v2
+
+The MAC addresses for lan/wan are swapped compared to the vendor
+firmware. This adjusts to vendor configuration, which is:
+
+lan *:7b label
+wan *:7c label+1
+2.4g *:7b label
+5g *:7a label-1
+
+Only one address is stored in <&mac 0x8>, corresponding to the label.
+
+This has been checked on revisions v1, v2 and v3.
+
+Since ar71xx calculates the ath10k MAC address based on the ethernet
+addresses, the number there is adjusted, too.

+Subject: ar71xx: remove wrong MAC address adjustment for Archer C60 v2
+
+The adjustment of the MAC address for Archer C60 v2 in 10_fix_wifi_mac
+is broken since a "mac" partition is not set up for this device on
+ar71xx. Instead, the MAC address is already patched correctly in
+11-ath10k-caldata.
+
+Remove the useless adjustment.
