[PATCH 14/21] drm/amd/display: Fix in secure display context creation

Rodrigo Siqueira Rodrigo.Siqueira at amd.com

From: Alan Liu <HaoPing.Liu at amd.com>

[Why & How]
We need to store CRTC information in secure_display_ctx, so postpone
the call to amdgpu_dm_crtc_secure_display_create_contexts() until we
initialize all CRTCs.
