drm/i915/gvt: Fix display port type issue
According to the vbt provided by GVT-g, the display output type should
be display port, instead of DVI. Currently, GVT-g display model only
supports display port emulation, not DVI or HDMI. This patch fixes this
by telling guest i915 the right output type supported by GVT-g.
v3: make port_b and port_c use dp type connector too. (Zhenyu)
v2: refine the commit message. (Zhenyu)
