Use https://github.com/pulp-platform/axi/tree/axi_lite_dw_converter/src, wait until it is merged into main in axi

I am jumping in and inform you that I found the following behavior in it. Basically, I can W/R the mailbox addressing it only using 32-bit instructions; otherwise, the mailbox is never addressed because the requests never reach it. Something happens between the data width converter and the axi to axi-lite. Need to deep investigate it.
