defconfig: sdm855: Enable msm_performance module

This module addresses the scenarios to meet power/perf needs
namely setting min/max frequencies based on userspace requests.

Userspace may need to set scaling_min/scaling_max for different
usecases based on perf/power requirement.
Currently available userspace nodes exposed by cpufreq framework
might not be appropriate in situations where userspace wants to
revert back its vote and the CPU in question is offline. This module
also adds support to set min/max limits on cpufreq for
different CPUs such that the module maintains the userspace vote
across hotplugs and applies it whenever CPU policy gets updated
(after it comes online).
