Michael Walle 7a1e4cb66b lm32: fix watchpoints 
The wp_match_n vector is off by one. Which results in undefined states, at
least in simulation.

Michael Walle a0ff666628 lm32: replace $clog2 with macro 
Unfortunately, XST does not support $clog2 with the localparam keyword
(the parameter keyword works just fine). Define a macro which replaces the
call with a constant function.

This commit can be reverted if the bug in XST is fixed.

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.
