Subject: [PATCH v1 00/10] mfd, x86: remove msic driver and leftovers

This is a second part of the Intel MID outdated platforms removal.
First part is available as immutable branch [1]. The series has functional
and build dependencies, so the mentioned branch should be used as a base
for these changes.

Note, that some of the drivers, that arch/x86 covers, seems never appeared
in the upstream (like msic_ocd).

There few ways are possible to proceed with this:
- extend existing immutable branch
- create another one based on MFD
- merge everything thru tip tree

I'm also all ears for alternatives.

The entire branch with all patches is available here [2].

Rafael, can you please help reviewing arch/x86 related code?
