Remove "High-DPI Support in Qt Quick Controls" doc page

It is probably wrong enough to require a thorough rewrite. Given that it has
nuggest such as "There is currently no available solution for high-DPI support
in applications wishing to mix Qt Quick Controls and Qt Quick Controls",
starting from scratch seems best.

-    \title High-DPI Support in Qt Quick Controls
-
-    Qt Quick Controls support Qt's cross-platform high-DPI scaling introduced in Qt 5.6.
-    The feature is opt-in, and can be enabled by setting the \c Qt::AA_EnableHighDpiScaling
-    application attribute in C++ before QGuiApplication is constructed:
-
-    \code
-    #include <QGuiApplication>
-    #include <QQmlApplicationEngine>
-
-    int main(int argc, char *argv[])
-    {
-        QGuiApplication::setAttribute(Qt::AA_EnableHighDpiScaling); // <--
-        QGuiApplication app(argc, argv);
-        QQmlApplicationEngine engine;
-        engine.load(QUrl(QStringLiteral("qrc:/main.qml")));
-        return app.exec();
-    }
-    \endcode
-
-    Alternatively, an environment variable \c QT_AUTO_SCREEN_SCALE_FACTOR=1 can be set
-    to enable automatic high-DPI scaling.
-
-    \warning \l {Qt Quick Controls}{Qt Quick Controls 1.x} are not compatible with Qt's
-    automatic high-DPI scaling. There is currently no available solution for high-DPI
-    support in applications wishing to mix Qt Quick Controls and Qt Quick Controls.
