Both videomode and display_timing contain flags describing the modes. These are stored in dmt_flags and data_flags. There's no need to separate these flags, and having separate fields just makes the flags more difficult to use. This patch combines the fields and renames VESA_DMT_* flags to DISPLAY_FLAGS_*.
