Symbian 5.3: QML text edit components are sending software input panel requests

The qdeclarativetextedit_p_p.h and qdeclarativetextinput_p_p.h files set default showInputPanelOnFocus as false in older Symbian platforms, but not in the the new 5.3 platform, causing software input panel requests to occur every time a QML text edit control gets focus, which causes undesired behavior - e.g. when application is brought to foreground and the focus is in text edit, it'll automatically open software input panel.

#ifdef Q_OS_SYMBIAN
        if (QSysInfo::symbianVersion() == QSysInfo::SV_SF_1 || QSysInfo::symbianVersion() == QSysInfo::SV_SF_3) {
            showInputPanelOnFocus = false;
        }
#endif

The version check can probably be removed completely.
