regulator: mc13783-regulator: correct the probing time.
When the mc13783-regulator driver is built in kernel, probing it during the regulator subsystem initialisation result in a fault. That is because regulator subsystem is planned to be initialised very early in the boot process, before the mfd subsystem initialisation. The mc12783-regulator probing process need to access to the mc13783-core functionality to read/write mc13783 registers and so must be called after the mc13783-core driver initialisation. The way to do this is to let the kernel probe the mc13783-regulator driver when mc13783-core register his regulator subdevice.
