mediatek: filogic: provide custom GPT table for Arcadyan Mozart

New revision Arcadyan Mozart apply a new partition table and moved the
factory partition to a new location. This conflicts with the standard
partition layout and also make the nvmem cells to not correctly identify
the MAC address anymore.

Generate and Provide a new GPT partition table that account for the new
calibration partition.
The previous revision of the Arcadyan Mozart device is considered
pre-production devices and should not be intended for real support.
