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.

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