Chander Sudanthi 61c14da751 O3: Remove hardcoded tgts_per_mshr in O3CPU.py.
There are two lines in O3CPU.py that set the dcache and icache
tgts_per_mshr to 20, ignoring any pre-configured value of tgts_per_mshr.
This patch removes these hardcoded lines from O3CPU.py and sets the default
L1 cache mshr targets to 20.
