Rafal Jaworowski ecb1ab1761 Obtain TSEC h/w address from the parent bus (OCP) and not rely blindly on what
might be currently programmed into the registers.

Underlying firmware (U-Boot) would typically program MAC address into the
first unit only, and others are left uninitialized. It is now possible to
retrieve and program MAC address for all units properly, provided they were
passed on in the bootinfo metadata.
