cpufreq: arm_big_little: add in-kernel switching (IKS) support
This patch adds IKS (In Kernel Switcher) support to cpufreq driver.
This creates a combined freq table for A7-A15 CPU pairs. A7 frequencies
are virtualized and scaled down to half the actual frequencies to
approximate a linear scale across the combined A7+A15 range. When the
requested frequency change crosses the A7-A15 boundary a cluster switch
is invoked.
Based on earlier work from Sudeep KarkadaNagesha.
