1c6f57cd6d dev: update LupIO-IPI device to latest specs 
The specs for the LupIO-IPI device were recently updated. Instead of
providing a single IPI value for each processor, the device now provides
32 individual IPI bits that can be masked and set.

Update device accordingly in gem5.

0800c060d8 dev: Fix cpu/reg decoding logic in multi-instance LupIO devices 
The current decoding logic is flawed and complicated to understand.
Using simple division and modulo instead; the compiler is smart enough
to generate efficient code since the divisor is a power of 2.

1c233ee9d2 scons: Add sim_object and enums arguments to SimObject(). 
This will explicitly declare what SimObject and Enum types need to be set
up in C++, which will make importing all the SimObject modules during
