soc: Add init_rom to initialize ROM and contents and with auto_size option (enable by default) to reduce ROM size to length of contents when in Read Only mode.
...
This ensures the integrated ROM is reduced to minimal size before build and avoid having to adjust it manually with --integrated-rom-size on targets.

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.
