net: tsec: Common handling of MAC station address for DM_ETH

In tsec_init, the MAC address is retrieved from 2 different structures
depending on whether DM_ETH is enabled or not.

But since the field name is the same inside both structures, we can
conditionally define the structure of the correct type and simplify the
assignments.
