For `XLEN = 64`, some tools (e.g. VCS) still elaborate the offset generation block for `XLEN = 32`, throwing an elaboration error (illegal bit access). Fix this by generating the AXI offset in an equivalent, parameter-agnostic and tool-friendly way. Signed-off-by: Nils Wistoff <[email protected]>

XLEN = 64, some tools (e.g. VCS) still elaborate the offset generation block forXLEN = 32, throwing an elaboration error (illegal bit access). Hence, VCS can currently not build the 64-bit WB configuration of CVA6. Fix this by generating the AXI offset in an equivalent, parameter-agnostic and tool-friendly way.
