[PATCH 03/40] abx500-chargalg: Store the AB8500 MFD parent device for platform differentiation

[lee.jones@linaro.org (Lee Jones)]

Any platform can be dynamically probed for model and version number
provided the AB8500 MFD parent device pointer is available. This
patch obtains that pointer and stores it in a locally controlled
struct for later use.
