flashchips: Remove 4-byte addressing flag for MT25QL128 and mark as tested
Using both a Dediprog SF100 and a Bus Pirate, read and erase works correctly
on a MT25QL128 but writes were failing to take effect. Currently, the entry
in flashchips.c indicates that this device supports 4-byte addressing.
Micron's datasheet indicates that it does not. After removing the 4-byte
addressing feature flag, both SF100 and Bus Pirate were able to successfully
read, erase, and write a MT25QL128 so also marking as tested.
