media: v4l: async: Also match secondary fwnode endpoints

[ Upstream commit 46347e3e ]

For camera sensor devices the firmware information of which comes from
non-DT (or some ACPI variants), the kernel makes the information visible
to the drivers in a form similar to DT. This takes place through device's
secondary fwnodes, in which case also the secondary fwnode needs to be
heterogenously (endpoint vs. device) matched.
