lantiq: Update TP-Link TD-W89x0 flash layout and convert to nvmem

Browse Source 
Flash space is scarce on 8MB devices, this commit adds 124KB of usable
space by reusing OEM user configuration and unused space. I also split
the partitions to seperate MAC Address & WPS key, Memory configuration,
and Wi-Fi calibration data.

This commit also switches from userspace script to using nvmem for ath9k
calibration data.
