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.

regulator: Set PROBE_PREFER_ASYNCHRONOUS for drivers that are newer than 6.1

This follows on the change ("regulator: Set PROBE_PREFER_ASYNCHRONOUS
for drivers that existed in 4.14") but changes regulators that were
not present in kernel 6.1.

regulator: max20411: Convert to i2c's .probe_new()

The probe function doesn't make use of the i2c_device_id * parameter so
it can be trivially converted.

regulator: max20411: Directly include bitfield.h

The max20411 driver uses bitfield.h but does not directly include
it, add an inclusion to avoid build errors in configurations
which do not result in an implicit inclusion.
