cpufreq: arm_big_little: add SCPI interface driver
On some ARM based systems, a separate Cortex-M based System Control
Processor(SCP) provides the overall power, clock, reset and system
control including CPU DVFS. SCPI Message Protocol is used to
communicate with the SCPI.
This patch adds a interface driver for adding OPPs and registering
the arm_big_little cpufreq driver for such systems.
