This is a faked configuration to evaluate the preprocessor stage in
xconversions.h and the ll_temac driver setup in
xilinx_ll_temac_standard_init().

I do not known any FPGA design / board on which I could test it in real
live. But I've run a simple test with BASEADDR1 set to same value of
BASEADDR. So I could test faked memory access to a single TEMAC in
hardware by two driver instance in software -- it works.

The ll_temac driver supports up to eight TEMAC entities in hardware.
That's why I've expand the faked Xilinx parameter list to eight.
