I don't notice a difference outside the margin of error. The Unixbench
workload reported 4550.4 with all configs, and 4550.9 with only
LLCC_CPUSS, LLCC_MDM, and LLCC_MMUHWT. My 15-second workload on
Hexagon/CDSP was half a second faster when commenting out the cache use
cases.

I don't see better startup times either.
