Over years alternate solutions have been designed and merged to deal with bL/HMP systems like EAS. Also since no other driver made use of generic arm_big_little cpufreq driver except Vexpress SPC, we can merge them together as vexpress-spc driver used only on Vexpress TC2(CA15_CA7) platform.

There are other qcom cpufreq socs like krait which does similar thing. Except for the interpretation of the read data, rest of the driver is same for both the cases. So pull the common things out for reuse.
