[FEATURE]Reduce the CPU_IF logic, use only AXI LITE

[roybod]

I have another tool called airhdl.com, that tool show exactly half LUT consumption.
it looks to me that is because of the internal implementation of the CPU_IF.
In the AIRHDL code, the only interface is the AXI LITE.
would you consider adding "remove CPU_IF feature" ?
