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 3e6de5d77a ("mediatek: use NVMEM framework on all Adtran
devices").
