From: Tom O'Rourke <Tom.O'Rourke@xxxxxxxxx>
When frequency requests are made by SLPC, host driver
should not attempt to make frequency requests due to
potential conflicts.
Host-based turbo operations are already avoided when
SLPC is used. This change covers other frequency
requests such as from sysfs or debugfs interfaces.
A later patch in this series updates sysfs/debugfs
interfaces for setting max/min frequencies with SLPC.
v2: Use intel_slpc_active instead of HAS_SLPC (Paulo)
