The SCU IPC functionality is usable outside of Intel MID devices. For example modern Intel CPUs include the same thing but now it is called PMC (Power Management Controller) instead of SCU. To make the IPC available for those split the driver into core part (intel_scu_ipc.c) and the SCU PCI driver part (intel_scu_pcidrv.c) which then calls the former before it goes and creates rest of the SCU devices. The SCU IPC will also register a new class that gets assigned to the device that is created under the parent PCI device. We also split the Kconfig symbols so that INTEL_SCU_IPC enables the SCU IPC library and INTEL_SCU_PCI the SCU driver and convert the users accordingly. While there remove default y from the INTEL_SCU_PCI symbol as it is already selected by X86_INTEL_MID.
