MC13783 can be programmed to wait some clock cycles between the
touchscreen polarization and the resistance conversion. This is
needed to adjust for touchscreens with high capacitance between
plates.

When the ADC is being prepared for a single or multiple channel reading,
the adc0 register is reconfigured without taking the lithium cell, charge
current and battery current reading enable bits into account. Which results
in clearing the bits.

This is needed to convert the touch driver away from using struct mc13783.

Note this patch drops MC13783_ADC0_ADREFMODE. This is unused and doesn't
exist on mc13892.

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.

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superseded mc13783 driver unchanged.
