linux-qoriq: move changes from staging to meta-mel

configurations required for systemd but Linux for FSL PPC is using SysVinit
instead of Systemd so this shouldn't be pushed upstream.

Enable vfat support for ppc

Instead of adding dosfstools to the image, add 'vfat' to MACHINE_FEATURES
which in turn includes dosfstools via packagegroup-base
