Some packages are missing in image of agl-demo-platform after moving to YP 2.1.1 'krogoth'.

Missing packages are followed:

libgstphotography-1.0-0
libqt5svg-plugins
libqt5svg5
qtmultimedia
qtmultimedia-plugins
qtmultimedia-qmlplugins
qtquickcontrols-qmlplugins 

This list is from diff of agl-demo-platform-porter.manifest.

These packages are from RDEPENDS only in ALS2016-demo.bb and CES2016-demo.bb.

RDEPENDS_${PN} += " \
    qtmultimedia-qmlplugins \
    qtquickcontrols-qmlplugins \
    qtsvg-plugins \
    "

Although root cause is unknown, it would be resolved if using 'als2016-demo' and 'ces2016-demo' as PN instead of capital ones.
