There are a lot of devices/drivers where they never have a struct device
created for them or the driver initializes the hardware without ever
binding to the struct device.

This series is intended to avoid any boot regressions due to such
devices/drivers when fw_devlink=on and also address the handling of
optional suppliers.

Patch 1 and 2 addresses the issue of firmware nodes that look like
they'll have struct devices created for them, but will never actually
have struct devices added for them. For example, DT nodes with a
compatible property that don't have devices added for them.

Patch 3 and 4 allow for handling optional DT bindings.

Patch 5 sets up a generic API to handle drivers that never bind with
their devices.

Patch 6 through 8 update different frameworks to use the new API.

This patchset fixes probing issue observed on various Exynos based 
boards even with commit c09a3e6c97f0 ("soc: samsung: pm_domains: Convert 
to regular platform driver") reverted. Thanks!
