The docs indicate that this should be a dual-BOOM and single-Rocket
config, with the Hwacha attached to the Rocket. However, the
'LargeBoomAndHwachaRocketConfig' config only has a single Rocket core.
Added the 'DualLargeBoomAndHwachaRocketConfig' config to accurately
reflect what's stated in the docs.
Additionally, this fixes hart numbering to place the Hwacha accelerator
on the Rocket core rather than on the BOOM core.
There were two problems here:
1. The docs indicated that this should be a dual-BOOM and
single-Rocket config, but the config actually had two Rocket
cores.
2. Since the doc include string was 'DualBoomAndRocket', it was
accidentally matching against the 'DualBoomAndRocketOneHwacha'
section, which comes first in the file.
So, I created a new 'DualLargeBoomAndSingleRocketConfig' config which
only has one Rocket core, and changed the doc include string to
'DualBoomAndSingleRocket'.
