drm/ast: Add support_wuxga flag to struct ast_device
Detect support for 1920x1200 (WUXGA) in ast_detect_widescreen(). The
flag is cleared by default. The test logic has been taken from existing
code in ast_crtc_helper_mode_valid(). The code in that function is being
replaced by the new flag.
v2:
- move shared detection code into helper (Jocelyn)
