Timers used for charging safety and maintenance must work even when
CPU power has collapsed. By using hrtimers with the realtime clock
the system is able to trigger an alarm that wakes-up the CPU and makes
it possible to handle events.
Allow a little slack time of 5 minutes for the hrtimers to allow CPU
to be woken-up in a more optimal power saving way. A 5 minute delay
to time-out timers relative to hours does not impact on safety.

AB8540 supports power path function in USB charging mode for fast
power up with dead and weak battery, and it could extend
the battery age.
When USB charging starts, if the Vbattrue is below than SW cut off
voltage, power path and pre-charge should be enabled. If Vbattrue
is higher than SW cut off voltage, power path and pre-charge should
be disabled. This is to make sure full current to battery charge.
At the end of charge, power path should be enable again to reduce
charging the battery again.

There is a forever loop calling iio_channel_release() because the
"chan < " part of the "chan < ARRAY_SIZE()" is missing. This is in both
the error handling on probe and also in the remove function.
The other thing is that it's possible for some of the elements of the
adc_bat->channel[chan] array to be an ERR_PTR(). I've changed them to be
NULL instead. We're still not allowed to pass NULLs to
iio_channel_release() so I've added a check.
Finally, I removed an unused "chan = ARRAY_SIZE(gab_chan_name);" statement

Power supply subsystem creates thermal zone device for the property
'POWER_SUPPLY_PROP_TEMP' which requires thermal subsystem to be ready
before 'ab8500 battery temperature monitor' driver is initialized. ab8500
btemp driver is initialized with subsys_initcall whereas thermal subsystem
is initialized with fs_initcall which causes
thermal_zone_device_register(...) to crash since the required structure
'thermal_class' is not initialized yet:

If charging is started before USB enumeration of an Accessory
Charger Adapter has finished, the AB8500 will generate a
VBUS_ERROR. This in turn results in timeouts and delays the
enumeration with around 15 seconds. This patch delays the
charging and then ramps currents slowly to avoid VBUS errors.
The delay allows the enumeration to have finished before
charging is turned on.

None of the aforementioned components have their own dedicated
platform data structures anymore. Instead they have all been
merged into one big Battery Management container. Let's remove
them and place all the nice newly added attributes into the core
container.
