regulator: Switch two more i2c drivers back to use .probe()

The previous conversion back to .probe done in commit 964e186547b2
("regulator: Switch i2c drivers back to use .probe()") was done based on
v6.3. Since then two more drivers were added which need to be convert
back in the same way before eventually .probe_new() can be dropped from
struct i2c_driver.
