of: Make OF framebuffer device names unique
Since Linux 5.19 this error is observed:
sysfs: cannot create duplicate filename '/devices/platform/of-display'
This is because multiple devices with the same name 'of-display' are
created on the same bus. Update the code to create numbered device names
for the displays.
Also, fix a node refcounting issue when exiting the boot display loop.
