viafb: simplify lcd size "detection"
viafb: simplify lcd size "detection" Remove all occurences of get_lcd_size_method as only the values GET_LCD_SIZE_BY_VGA_BIOS and GET_LCD_SIZE_BY_USER_SETTING were used which had the identical code so there is no need to make things look more complicated than they actually are. Just a bit of of cleanup, really no regressions expected. Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de> Cc: Joseph Chan <JosephChan@via.com.tw>
