econet: standardize partitions in DTS files

In preparation for the introduction of ethernet, this patch normalizes the
partitions in the devices in DT so that the partition to upgrade will
always be called tclinux, no matter what it is called from the factory.
Also fix a math error in Nokia G240G-E partition table and remove leading
zeros from paritition offsets.

Finally, add NVMEM mac-address entries where they are left by the
factory. In preparation for the introduction of Ethernet and Wifi
support.
