Intel MSIC MFD driver for Medfield platform

Hi,

This series adds support for the Intel MSIC (Mixed Signal IC) chip found on
Intel Medfield platforms. The MSIC chip embeds audio codec, ADC, GPIOs etc.

Existing drivers which use plain SCU IPC will continue to work and they can
be converted to the MSIC register interface later on. Any new drivers for
devices in the MSIC should use this interface.

Thanks.
