drm/ast: Add support_fullhd flag to struct ast_device

Browse source

Detect support for 1920x1080 (FullHD) 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.

For Gen3, a new branch duplicates the Gen2 logic and adds a test for
AST2200. Gen2 adds a test for AST2100.

v2:
- use fullhd flag for setting max width/height
