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.
