HISI LPC: Add Kconfig MFD_CORE dependency
For ACPI support of the HiSilicon LPC driver we depend on MFD_CORE config. Currently the HiSi LPC Kconfig entry does not define this dependency, so add it. The reason for depending on MFD_CORE in the driver is that we model the LPC host as an MFD, in that a platform device will be created for each device on the bus. We do this as we need to modify the resources of these derived platform devices, something which we should not do to the original devices created in the ACPI scan. Details in e0aa1563f894 ("HISI LPC: Add ACPI support").
