Here's all of my third attempt at MFD cell sharing.  This includes all
parts; some of the patches from v2 are being resent without changes.  I
apologize for the noise, but since I screwed up the threading in the first 
batch and people were having trouble finding some of the patches, I figured
I'd resend everything together.  There are some changes in there as well;
they've been marked in commit messages.

This whole set does the following things:
 - make mfd_cell structs always accessible to platform devices
 - adjust the mfd_cell API to (hopefully) be cleaner, replacing platform_data
and driver_data with mfd_data
 - add wrapper functions to access mfd cell and data fields
 - adjust all mfd clients/drivers to use the new API
 - add a reference counting wrapper for mfd_cell's enable/disable hooks
 - add platform device sharing wrappers to allow mfd clients to create
   new platform devices (at the same time as platform drivers are being
 - update the cs5535-mfd driver (and clients) to make use of the new
   sharing code

This effectively provides the ability for mfd clients to share a single 
mfd_cell, and provide the framework for mfd-core be handle shared hardware
