drm/i915/hdcp: No direct access to power_well desc

Browse Source 
HDCP code doesn't require to access power_well internal stuff,
instead it should use the intel_display_power_well_is_enabled()
to get the status of desired power_well.
No functional change.

v2:
- used with_intel_runtime_pm instead of get/put. [Jani]
v3:
- rebased.
