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. Reviewed by: imp, marcel Approved by: cognet (mentor)
