...
Useful for standalone core where the user logic can be looking at init_done/init_error to
condition user accesses.

xics: Disable endianness swapping
...
The endianess swapping code caused the core to diverge from microwatt resulting in:
- The xics tests not working as-is: https://github.com/antonblanchard/microwatt/blob/master/tests/xics/xics.h
- byte writes writing to the incorrect byte
This removes endianswapping and minimizes the delta from upstream for the xics irq.h header.

Example of use:
$litex_sim
$litex_bare_metal_demo --build-path=build/sim
$litex_sim --ram-init=demo.bin
Press Esc during the LiteX boot.
