commit 374de39d38f97b0e58cfee88da590b2d056ccf7f upstream.
Currently, The imx pgc power domain doesn't set the fwnode pointer, which results in supply regulator device can't get consumer imx pgc power domain device from fwnode when creating a link.
This causes the driver core to instead try to create a link between the parent gpc device of imx pgc power domain device and supply regulator device. However, at this point, the gpc device has already been bound, and the link creation will fail. So adding the fwnode pointer to the imx pgc power domain device will fix this issue.
