regulator: tps65185: check devm_kzalloc() result in probe

tps65185_probe() dereferences the allocation result immediately by using data->regmap. If devm_kzalloc() returns NULL under memory pressure, this leads to a NULL pointer dereference.

Add the missing allocation check and return -ENOMEM on failure.
