cpufreq: ARM big LITTLE: Fix Kconfig entries

This fixes usage of "depends on" and "select" options in Kconfig for ARM big
LITTLE cpufreq driver. Otherwise we get these warnings:

warning: (ARM_DT_BL_CPUFREQ) selects ARM_BIG_LITTLE_CPUFREQ which
has unmet direct dependencies (ARCH_HAS_CPUFREQ && CPU_FREQ && ARM &&
ARM_CPU_TOPOLOGY)
