This reverts commit 3b98c93525.
Russell says:
Using devm_*() [here] is completely wrong, because this is called
from mdiobus_register_device(). This is not the probe function
for the device, and thus there is no code to trigger the release of
the resource on unregistration.
Moreover, when the mdiodev is eventually probed, if the driver fails
or the driver is unbound, the GPIO will be released, but a reference
will be left behind.
Using devm* with a struct device that is *not* currently being probed
is fundamentally wrong - an abuse of devm.
