mediatek: filogic: convert Acer Predator W6 to use NVMEM framework

Read WiFi calibration data via NVMEM framework. The MAC addresses are stored inside a file on a filesystem and hence still have to be extracted in userspace. WiFI EEPROM extraction has already accidentally been partially removed by commit 3e6de5d ("mediatek: use NVMEM framework on all Adtran devices"). Fixes: 3e6de5d ("mediatek: use NVMEM framework on all Adtran devices") Signed-off-by: Daniel Golle <[email protected]>
