Browse source 
Update the get/set min/max freq hooks to work for
SLPC case as well. Consolidate helpers for requested/min/max
frequency get/set to intel_rps where the proper action can
be taken depending on whether SLPC is enabled.

v2: Add wrappers for getting rp0/1/n frequencies, update
softlimits in set min/max SLPC functions. Also check for
boundary conditions before setting them.

v3: Address review comments (Michal W)

v4: Add helper for host part of intel_rps_set_freq helpers (Michal W)

v5: checkpatch()
