Subject: [PATCH] udev-rules-rpi.bb: Fix psplash systemd connection

Add udev rule to notify systemd of available fb

When using psplash in combination with systemd the splash screen is not
shown. The dependency to sys-devices-platform-gpu-graphics-fb0.device
will terminate psplash-start.service because systemd is not aware of the
existing framebuffer device node.
