Subject: drm/amd/display: Fix in secure display context creation
From: Alan Liu <HaoPing.Liu@xxxxxxx>
commit f477c7b5ec3e4ef87606671b340abf3bdb0cccff upstream.
[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.
