[Intel-gfx] [PATCH] drm/i915: fix the issue DP-1 not working in guest

[Mustamin B Mustaffa]

From: "Anuar, Nuhairi" <nuhairi.anuar at intel.com>

In GVT guest, when port A is DP, i915 will force it as an EDP panel,
which
will cause DP-1 not working in GVT guest.
This patch fixed this issue by check intel_vgpu_active() in
intel_ddi_compute_config().
