driver core: avoid repeatedly printing the same 'Fixed dependency' log

Browse source

The "Fixed dependency cycle(s) with ..." log is printed for each cycle
finding process. In particular, the same cycle may be parsed many times
during the proxy link setup. For example, if /soc/bus@4c000000/usb@4c100000
is a devicetree structure and node usb@4c100000 is in a cycle, then for
each device registration (soc, 4c000000.bus and 4c100000.usb),
fw_devlink_create_devlink() will find the same cycle and print a log.
The repeat logs are redundant and may cause confusion for the user. Move
the pr_debug() to __fwnode_link_cycle() and avoid printing the log if it
has already been printed.
