Michael Walle 10495e72d0 lm32: rename mem array in lm32_dp_ram 
Be compatible with original proprietary DP RAM instantiation. This is
needed for simulation, where r0 is initialized to zero in lm32_cpu.v.

Michael Walle 47baad4fe1 lm32: replace clogb2 by builtin $clog2 
This function is fixed in ISE since version 14.1 (see AR #44586). If the
builtin function is used, the design can be simulated with Icarus Verilog.
