power: twl4030_charger: detect battery presence prior to enabling charger TWL4030's Battery Charger seems to be designed for non-hotpluggable batteries. If battery is not present in the system, BATSTS is always set with the expectation that software will take actions to move to a required safe state (could be power down or disable various charger paths). It does not seem possible even by manipulating the edge detection of the event (using BCIEDR2 register) to have a consistent hotplug handling. This seems to be the result of BATSTS interrupt generated when the thermistor of the battery pack is disconnected from the dedicated ADIN1 pin. Clearing the status just results in the status being regenerated by the monitoring ADC(MADC) and disabling the edges of event just makes hotplug no longer function. The only other option is to disable the detection of the MADC by disabling BCIMFEN4::BATSTSMCHGEN (battery presence detector) - but then, we can never again detect battery reconnection. So, detect battery presence based on precharge(which is hardware automatic state) or default main charger configuration at the time of probe and enable charger logic only if battery was present.

twl4030_charger: Remove unnecessary platform_set_drvdata() The driver core clears the driver data to NULL after device_release or on probe failure, since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d (device-core: Ensure drvdata = NULL when no driver is bound).
