power: regulator: tps62360_regulator: Convert ofdata_to_platdata to the missing probe

commit 29f7d05a347a ("dm: core: Move ofdata_to_platdata() call earlier")
introduces changes in the order of device_probe execution.
ofdata_to_platdata now comes before the probe function which resulted in
a deadlock and caused boot hang on AM6 devices.

Deadlock sequence: tps62360_regulator_ofdata_to_platdata --> i2c_get_chip
--> device_probe(tps62360) --> tps62360_regulator_ofdata_to_platdata

Hence convert ofdata_to_platdata to the missing probe function to fix the
hang.
