[PATCH 4/5] drm/sti/sti_hdmi: Replace drm_detect_hdmi_monitor() with is_hdmi

[José Expósito]

Once EDID is parsed, the monitor HDMI support information is available
through drm_display_info.is_hdmi.

This driver calls drm_detect_hdmi_monitor() to receive the same
information and stores its own cached value, which is less efficient.

Avoid calling drm_detect_hdmi_monitor() and use drm_display_info.is_hdmi
instead and also remove sti_hdmi.hdmi_monitor as it is no longer
necessary.
