mfd: Fix memleak in pcf50633_client_dev_register
Since platform_device_add_data copies the passed data, the allocated
subdev_pdata is never freed. A simple fix would be to either free subdev_pdata
or put it onto the stack. But since the pcf50633 child devices can rely on
beeing children of the pcf50633 core device it's much more elegant to get access
to pcf50633 core structure through that link. This allows to get completly rid
of pcf5033_subdev_pdata.

pcf50633: Get rid of charging restart software auto-triggering
After reaching Battery Full condition MBC state machine switches back
into charging mode when the battery voltage falls below 96% of a
battery float voltage. The voltage drop in Li-Ion batteries is
marginal (1-2%) till about 80% of its capacity - which means, after a
BATFULL, charging won't be restarted until 75-80%.
That is a desired behaviour recommended by battery manufacturers,
don't mess with it.

pcf50633: introduces battery charging current control
Implement a new sysfs attribute to allow changing MBC charging limit on
the fly independently of usb current limit. It also gets set
automatically every time usb current limit is changed.
Limiting charging current also prevents violating USB specification in
the case when the whole device is shut down and usb current limit is
reset to the factory default by the pcf50633 state transition.

mfd: use a dedicated workqueue for pcf50633 irq processing
Using the default kernel "events" workqueue causes problems with
synchronous adc readings if initiated from some task on the same
workqueue.
I had a deadlock trying to use pcf50633_adc_sync_read from a
power_supply class driver because the reading was initiated from the
workqueue and it waited for the irq processing to complete (to get the
result) and that was put on the same workqueue.

pcf50633_charger: Enable periodic charging restart
The battery charger state machine switches into charging mode when
the battery voltage falls below 96% of a battery float voltage. But
the voltage drop in Li-ion batteries is marginal(1~2 %) till about
80% of its capacity - which means, after a BATFULL, charging won't
be restarted until 80%.
This work_struct function restarts charging at regular intervals to
make sure the battery doesn't discharge too much.
