mfd: intel_soc_pmic_crc: Merge Intel PMIC core to crc
The core part is misleading since its only purpose to serve Crystal Cove PMIC, although for couple of different platforms. Merge core part into crc one. Advantages among others are: - speed up a compilation and build - decreasing the code base - reducing noise in the namespace by making some data static and const Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Tested-by: Hans de Goede <hdegoede@redhat.com> Reviewed-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Lee Jones <lee@kernel.org> Link: https://lore.kernel.org/r/20220801114211.36267-2-andriy.shevchenko@linux.intel.com
