 leon,greth: added support for variable sized descriptor table sizes

 The descriptor table size is equal to its alignment and set when
 configuring the HW IP through VHDL generics. This SW patch simply
 probes the HW how large the RX/TX descriptor tables are and adjusts
 accordingly.

 The number of descriptors actual used are controlled by other
 settings (rxDescs and txDescs) controlled by the user.

 Update #4308.
