regulator: Switch i2c drivers back to use .probe() 
After commit b8a1a4cd5a ("i2c: Provide a temporary .probe_new()
call-back type"), all drivers being converted to .probe_new() and then
03c835f498 ("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: rt5759: fix OOB in validate_desc() 
I got the following OOB report:

The desc used in validate_desc() is passed from 'reg_cfg.ena_gpiod',
which is not initialized. Fix this by initializing 'reg_cfg' to 0.
