Subject: [PATCH 06/11] phy: un-inline devm_mdiobus_register()

From: Bartosz Golaszewski <bgolaszewski@...libre.com>

Functions should only be static inline if they're very short. This
devres helper is already over 10 lines and it will grow soon as we'll
be improving upon its approach. Pull it into mdio_devres.c.
