The intel_pmc_core driver did not always bind to a device which meant it lacked a struct device that could be used to maintain driver data. So a global instance of struct pmc_dev was used for this purpose and functions accessed this directly. Since the driver now binds to an ACPI device, remove the global pmc_dev in favor of one that is allocated during probe. Modify users of the global to obtain the object by argument instead.
