Commit343a8d17fa(cpufreq: scpi: remove arm_big_little dependency) removed the SCPI cpufreq dependency on arm_big_little cpufreq driver. However the Kconfig entry still depends on ARM_BIG_LITTLE_CPUFREQ which is clearly wrong. This patch removes that unnecessary Kconfig dependency.

Collaborative Processor Performance Controls. It

performance values which allows the remote power

processor to flexibly optimize for power and
