Store a pointer to the pdata so that if it needs to be used after probe it can be. In the case of booting from DeviceTree, the dev.platform_data may be null, so we need to store this pointer explicitly.
Based on work by Joseph Lo.

v2: - Renamed patch from "regulator: palmas: fix pdata ptr not be updated after it has been allocated" to be appropriate to the current change. - Instead of updating dev.platform_data, store the pdata pointer in the pmic struct which we already have access to via drvdata.
