[PATCH v7 1/3] Revert "treewide: Fix probing of devices in DT overlays"

[Herve Codina <herve.codina@bootlin.com>]

From: Saravana Kannan <saravanak@google.com>

This reverts commit 1a50d9403fb90cbe4dea0ec9fd0351d2ecbd8924.

While the commit fixed fw_devlink overlay handling for one case, it
broke it for another case. So revert it and redo the fix in a separate
patch.
