Setting voltage, enabling/disabling regulators requires operations on all regulators related with the regulator being changed. Therefore, all of them should be locked for the whole operation. With the current locking implementation, adding additional dependency (regulators coupling) causes deadlocks in some cases. Introduce a possibility to attempt to lock a mutex multiple times by the same task without waiting on a mutex. This should handle all reasonable coupling-supplying combinations, especially when two coupled regulators share common supplies. The only situation that should be forbidden is simultaneous coupling and supplying between a pair of regulators. The idea is based on clk core.
