ubnt-ledbar: adapt for kernel v6.6

Linux kernel commit torvalds/linux@b8a1a4cd5a98a2adf8dfd6902cd98e57d910ee12
added a temporary probe_new member to struct i2c_driver, to drop the
rarely used second parameter of the probe function and not break API for
out of tree drivers. With torvalds/linux@5eb1e6e459cfa025f79c43014f66ff62a55542f1,
which is part of v6.6, this probe_new member is dropped and the
signature of the probe function is updated.

ubnt-ledbar is used by the mediatek and ramips targets and both have
been updated to v6.6, so adapt the probe function signature and remove
other compat code for versions before v6.6.
