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 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.
