ID widths smaller than 4 cause out-of-bound indexing warning/error

[ricted98]

The following parameter is set to 4 and cannot be changed via external parametrization if I am not mistaken:

axi_llc/src/axi_llc_pkg.sv

Line 235 in 0c581ed

parameter int unsigned UseIdBits = 32'd4;

If an ID width smaller than 4 is used, the following instantiation of AXI demux will throw errors due to out of bound indexing:

axi_llc/src/axi_llc_top.sv

Line 473 in 0c581ed

.AxiLookBits ( axi_llc_pkg::UseIdBits ),
