Revert "ramips: mt7620: fix patching mac address in caldata"

This reverts commit 3295f6f1c254cd7e5e5285a05581bf6abbde8999.

It looks like the eeprom gets broken after this change.
I think this change was not tested on a real device before it was
merged.
The MAC addresses will be broken again after this revert.
