cpufreq: Remove unnecessary use of policy->shared_type
policy->shared_type field was added only for SoCs with ACPI support:
commit 3b2d99429e3386b6e2ac949fc72486509c8bbe36
Author: Venkatesh Pallipadi <venkatesh.pallipadi@intel.com>

P-state software coordination for ACPI core
http://bugzilla.kernel.org/show_bug.cgi?id=5737
Many non-ACPI systems are filling this field by mistake, which makes its usage
confusing. Lets clean it.
