Is anyone aware if a separate step that is required to bind the device to the driver? I've tried
sudo sh -c 'echo -n 1-2.2.1 > /sys/bus/gbphy/drivers/gpio/bind'

It should "just work" if the manifest signatures match the what the greybus gpio driver expects.
Do you get any logging messages in your kernel log when you do this?
The bundle class in the manifest was incorrect. Should have been 0x0a (bridged phy) - GPIO protocol is a go ;-)
