clk: versaclock3: Switch to use i2c_driver's probe callback

The previous mass switch of clk drivers done in commit 62279db5a323
("clk: Switch i2c drivers back to use .probe()") was based on v6.4-rc1
Since then this driver was added which needs to be converted back in the
same way before eventually .probe_new() can be dropped from struct
i2c_driver.
