This patch converts the drivers in drivers/mfd/* to use module_pci_driver()
macro which makes the code smaller and a bit simpler.

The cs5535-pms cell doesn't actually need to be cloned, so we can drop that
and simply have the olpc-xo1.c driver use "cs5535-pms" directly.

Also, rename the cs5535-acpi clones to what we actually use for the (currently
out-of-tree) SCI driver.  In the process, that fixes a subtle bug in
olpc-xo1.c which broke powerdown on XO-1s.. olpc-xo1-ac-acpi was a typo, not
something that actually existed.

Replace mfd_shared_platform_driver_register with mfd_clone_cell.  The
former was called by an mfd client, and registered both a platform driver
and device.  The latter is called by an mfd driver, and registers only a
platform device.

The downside of this is that mfd drivers need to be modified whenever
new clients are added that share a cell; the upside is that it fits
Linux's driver model better.  It's also simpler.

This also converts cs5535-mfd/olpc-xo1 from the old API.  cs5535-mfd
now creates the olpc-xo1-{acpi,pms} devices, while olpc-xo1 binds to
them via platform drivers.

This enables sharing of cs5535-mfd cells via the new mfd_shared_* API.
Hooks for enable/disble of resources are added, with refcounting of
resources being automatically handled so that cs5535_mfd_res_enable/disable
are only called when necessary.

Clients of cs5535-mfd (in this case, olpc-xo1.c) are also modified to
use the mfd_shared API.  The platform drivers are also renamed to
olpc-xo1-{pms,acpi}, and resource enabling/disabling is replaced
with mfd_shared API calls.

Add an MFD driver to handle the ISA device on CS5535 and CS5536
southbridges. This ISA bridge is actually multiple devices: GPIOs,
MFGPTs, etc.
