ath79: Read MAC addresses from flash in 11-ath10k-caldata

In commit c3a8518 eth0 and eth1 have been swapped for some devices,
but 11-ath10k-caldata has not been updated.
Instead of fixing this by swapping eth0/eth1, this patch will read
addresses from flash (as done for several devices already) so
adjustments due to eth order become obsolete.
