soc/intel/cmn/gfx: Detect dual display (eDP + HDMI)
This patch adds support for detecting dual displays (eDP and HDMI) on
Intel platforms. This information is useful for setting the
`lb_framebuffer.has_external_display` variable, which is used to
determine whether depthchage should avoid shutting down when an
extended display is present.
TEST= Able to build and boot google/rex, where depthchage now
successfully avoids shutting down when both eDP and HDMI displays
are attached.
w/o this patch:
with eDP and HDMI attached: .has_external_display=0
with eDP attached: .has_external_display=0
with HDMI attached: .has_external_display=1
w/ this patch:
with eDP and HDMI attached: .has_external_display = 1
with eDP attached: .has_external_display=0
with HDMI attached: .has_external_display=1
