[PATCH v2 2/4] Revert "net: mdio: Delete usage of driver_deferred_probe_check_state()"

[Saravana Kannan]

This reverts commit f8217275b57aa48d98cc42051c2aac34152718d6.

There are a few more issues to fix that have been reported in the thread
for the original series [1]. We'll need to fix those before this will work.
So, revert it for now.
