It is logical to cleanup in probe's error path in reverse order to
previous actions. It also makes easier to add additional goto labels
within this error path.

If kstrtoul() fails then we print "charge_full" when it's uninitialized.
The debug printk doesn't add anything so I deleted it and cleaned these
two functions up a bit.

getnstimeofday64() is deprecated in favor of the ktime_get() family.
The direct replacement would be ktime_get_real_ts64(), but we only need
the seconds value, and it seems better to use boottime than real time
to avoid unexpected behavior with a concurrent settimeofday().
ktime_get_seconds() might also work, but it seems better to use
boottime than monotonic time since I assume that the charging
process continues during suspend.

The AB8540 was an evolved version of the AB8500, but it was never
mass produced or put into products, only reference designs exist.
The upstream support was never completed and it is unlikely that
this will happen so drop the support for now to simplify
maintenance of the AB8500.

In drivers/power/supply/ab8500_fg.c, fix two typos and adjust the function
name in two cases to correspond to the names of the defined functions.
In drivers/power/supply/power_supply_core.c, change two variable names to
the names of the corresponding parameters.

alloc_ordered_workqueue() with WQ_MEM_RECLAIM set replaces
deprecated create_singlethread_workqueue(). This is the identity
conversion.
The workqueue "fg_wq" is used for running the FG algorithm periodically.
It has been identity converted.
It has multiple work items viz fg_periodic_work, fg_low_bat_work,
fg_reinit_work, fg_work, fg_acc_cur_work and fg_check_hw_failure_work,
which require execution ordering. Hence, a dedicated ordered workqueue
has been used here.
The WQ_MEM_RECLAIM flag has been set to guarantee forward progress under
memory pressure.

This moves all power supply drivers from drivers/power/
to drivers/power/supply/. The intention is a cleaner
source tree, since drivers/power/ also contains frameworks
unrelated to power supply, like adaptive voltage scaling.
