Discrepancy between data width of oc-accel config and generic in action_types.vhd causes simulation to silently fail

[joosthooz]

If the data width differs between the config of oc-accel (the option in the menuconfig to select between 1024 and 512 bits) and the C_M_AXI_HOST_MEM_DATA_WIDTH generic in action_types.vhd, there is no error or warning, the simulation will start (seemingly without problems), but the application will just not work.
