cpufreq: vexpress-spc: Switch cpumask from topology core to OPP sharing
Since commit ca74b316df96 ("arm: Use common cpu_topology structure and functions.") the core cpumask has to be modified during cpu hotplug operations. So using them to set up cpufreq policy cpumask may be incorrect as it may contain only cpus that are online at that instance. Instead, we can use the cpumask setup by OPP library that contains all the cpus sharing OPP table using dev_pm_opp_get_sharing_cpus.
