[PATCH] mfd/ASoC: WM8400: select SND_SOC_WM8400 from MFD_WM8400

[Piyush Patle <piyushpatle228@gmail.com>]

The MFD driver wm8400-core.c unconditionally registers a platform
device named 'wm8400-codec' via wm8400_register_codec(). The codec
driver in sound/soc/codecs/wm8400.c binds to this device by name,
but SND_SOC_WM8400 is a hidden symbol with no prompt and nothing
was selecting it in normal configurations, so the driver never built.

Fix this by adding 'select SND_SOC_WM8400' to MFD_WM8400, which
encodes the implicit dependency that already existed at runtime.
Also remove the FIXME comment that noted this gap.
