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

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.

Be compatible with original proprietary DP RAM instantiation. This is
needed for simulation, where r0 is initialized to zero in lm32_cpu.v.

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.
