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.

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.
