[PATCH v4] mfd: intel_soc_pmic: Fix a mess with compilation units

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

Crystal Cove and Whiskey Cove are two different PMICs which are
installed on Intel Atom SoC based platforms.

Moreover there are two independent drivers that by some reason were
supposed (*) to get into one kernel module.

Fix the mess by clarifying Kconfig option for Crystal Cove and split
Whiskey Cove out of it.

(*) It looks like the configuration was never tested with
    INTEL_SOC_PMIC=n. The line in Makefile is actually wrong.

 - fix dependency for now, proper fix is to provide headers in platform_data/x86
 - add tags
