Re: [PATCH v1 1/2] driver core: fw_devlink: Allow firmware to mark devices as best effort

When firmware sets the FWNODE_FLAG_BEST_EFFORT flag for a fwnode,
fw_devlink will do a best effort ordering for that device where it'll
only enforce the probe/suspend/resume ordering of that device with
suppliers that have drivers. The driver of that device can then decide
if it wants to defer probe or probe without the suppliers.

This will be useful for avoid probe delays of the console device that
were caused by commit 71066545b48e ("driver core: Set
fw_devlink.strict=1 by default").

Fixes: 71066545b48e ("driver core: Set fw_devlink.strict=1 by default")
