net: airoha: Move net_devs registration in a dedicated routine

Browse source

[ Upstream commit 5e7365b5a1 ]

Since airoha_probe() is not executed under rtnl lock, there is small race
where a given device is configured by user-space while the remaining ones
are not completely loaded from the dts yet. This condition will allow a
hw device misconfiguration since there are some conditions (e.g. GDM2 check
in airoha_dev_init()) that require all device are properly loaded from the
device tree. Fix the issue moving net_devices registration at the end of
the airoha_probe routine.
