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.

v1: Use intel_slpc_active instead of HAS_SLPC (Paulo)

All of the other checks in rps are enabled, right?

Will change this to make consistent.
