Expand the specific configuration for the microblaze-generic board in xparameters.h with a faked setup to enable the LL_TEMAC driver.
Note: From now the microblaze-generic board is no longer a valid board configuration for a real piece of hardware. Rather than, we use the file config.mk and xparameters.h as a faked board configuration to force the compilation of all potential driver code for Microblaze systems.

Do these two options test anything?
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 same here.
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.
