mfd: si476x: Add header files and Kbuild plumbing

Browse source 
This patch adds all necessary header files and Kbuild plumbing for the
core driver for Silicon Laboratories Si476x series of AM/FM tuner
chips.

The driver as a whole is implemented as an MFD device and this patch
adds a core portion of it that provides all the necessary
functionality to the two other drivers that represent radio and audio
codec subsystems of the chip.

This is the core driver for the SI476x series of AM/FM
radio. This MFD driver connects the radio-si476x V4L2 module
and the si476x audio codec.
To compile this driver as a module, choose M here: the
module will be called si476x-core.
