[PATCH] drm/drm_connector: add additional aspect ratio values

[Wayne Lin]

For HDMI2.0 CTS item - HF1-35, it verifies if the source generates
video timing "64:27" video format correctly.

eg: (vic-76) 1920x1080p at 60Hz,24bpp

This patch add on "64:27" and "256:135" to drm_aspect_ratio_enum_list.
Thereafter, one can specify the aspect ratio to "64:27" or "256:135"
after creating aspect ratio property.
