Subject: [PATCH v2] mfd: intel_soc_pmic: Fix a mess with compilation units

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 are
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 ever tested. The line in
    Makefile is actually wrong.
