Those regulators are not actually supported by the AB8500 regulator
driver. There is no ab8500_regulator_info for them and no entry in
ab8505_regulator_match.
As such, they cannot be registered successfully, and looking them
up in ab8505_regulator_match causes an out-of-bounds array read.
Fixes: 547f384f33 ("regulator: ab8500: add support for ab8505")
