Samuel Ortiz c8a03c96b6 mfd: Use mfd cell platform_data for mc13xxx cells platform bits
With the addition of a platform device mfd_cell pointer, MFD drivers
can go back to passing platform data back to their sub drivers.
This allows for an mfd_cell->mfd_data removal and thus keep the
sub drivers MFD agnostic. This is mostly needed for non MFD aware
sub drivers.

Axel Lin 6991ec255a mfd: Add MODULE_DEVICE_TABLE to mc13xxx-core
The device table is required to load modules based on modaliases.
After adding the MODULE_DEVICE_TABLE, below entries will be added to
modules.alias:
alias spi:mc13892 mc13xxx_core
alias spi:mc13783 mc13xxx_core

Andres Salomon 65e523595a mfd: Rename platform_data field of mfd_cell to mfd_data
Rename the platform_data variable to imply a distinction between
common platform_data driver usage (typically accessed via
pdev->dev.platform_data) and the way MFD passes data down to
clients (using a wrapper named mfd_get_data).

All clients have already been changed to use the wrapper function,
so this can be a quick single-commit change that only touches things
in drivers/mfd.

Andres Salomon 4ec1b54c4d mfd: mfd_cell is now implicitly available to mc13xxx drivers
The cell's platform_data is now accessed with a helper function;
change clients to use that, and remove the now-unused data_size.

Note that mfd-core no longer makes a copy of platform_data, but the
mc13xxx-core driver creates the pdata structures on the stack.  In
order to get around that, the various ARM mach types that set the
pdata have been changed to hold the variable in static (global) memory.
Also note that __initdata references in aforementioned pdata structs
have been dropped.

Uwe Kleine-König 8e00593557 mfd: Add mc13892 support to mc13xxx
mc13892 is the companion PMIC for Freescale's i.MX51.  It's similar enough
to mc13782 to support it in a single driver.

This patch introduces enough compatibility cruft to keep all users of the
superseded mc13783 driver unchanged.
