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

After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new()
call-back type"), all drivers being converted to .probe_new() and then
03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert
back to (the new) .probe() to be able to eventually drop .probe_new() from
struct i2c_driver.

Use a local variable instead is enough, this simplifies the code.

regulator: rt6160: Add support for Richtek RT6160

Add support for Richtek RT6160 voltage regulator. It can provide up
to 3A output current within the adjustable voltage from 2025mV
to 5200mV. It integrate a buckboost converter to support wide input
voltage range from 2200mV to 5500mV.
