gianfar: Make MAC addr setup endian safe, cleanup

Fix the 32-bit memory access that is not endian safe,
i.e. not giving the desired byte layout for a LE CPU:
tempval = *((u32 *) (tmpbuf + 4)), where 'char tmpbuf[]'.

Get rid of rendundant local vars (tmpbuf[] and idx) and
forced casts.  Cleanup comments.
