[PATCH 6.6 256/261] drm/i915/hdcp: Move to using intel_display in intel_hdcp

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

6.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Suraj Kandpal <suraj.kandpal@intel.com>

[ Upstream commit e35bf8f6a0ff06ceeff15bb032351cd5d006f92b ]

Move to using intel_display wherever possible in intel_hdcp.c
as a part of code refactor.

--v2
-Move intel_display to the first line wherever possible [Jani]
-use the closest reference when using to_intel_display [Jani]
