[PATCH v2] drm/gma500: replace drm_detect_hdmi_monitor() with drm_display_info.is_hdmi

[Tejas Vipin <tejasvipin76@gmail.com>]

Replace drm_detect_hdmi_monitor() with drm_display_info.is_hdmi since
monitor HDMI information is available after EDID is parsed. Additionally
rewrite the code the code to have fewer indentation levels.

    - Use drm_edid instead of edid
