Use the device lifecycle managed register function. This helps prevent
mistakes like unregistering out of order in cleanup functions and
forgetting to unregister on error paths.

returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() is renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

The print function dev_err() is redundant because
platform_get_irq() already prints an error.
Eliminate the follow coccicheck warning:
./drivers/power/supply/goldfish_battery.c:225:2-9: line 225 is
redundant because platform_get_irq() already prints an error

Since ACPI_PTR() is used to NULLify the value when !CONFIG_ACPI, the
struct acpi_device_id becomes unused:
drivers/power/supply/goldfish_battery.c:269:36: warning:
'goldfish_battery_acpi_match' defined but not used [-Wunused-const-variable=]

spdxcheck.py complains:
drivers/power/supply/goldfish_battery.c: 1:28 Invalid License ID: GPL
which is correct because GPL is not a valid identifier. Of course this
could have been caught by checkpatch.pl _before_ submitting or merging the
patch.
WARNING: 'SPDX-License-Identifier: GPL' is not supported in LICENSES/...
#19: FILE: drivers/power/supply/goldfish_battery.c:1:
+// SPDX-License-Identifier: GPL
Which is absolutely hillarious as the commit introducing this wreckage says
in the changelog:
There was a checkpatch complain:
"Missing or malformed SPDX-License-Identifier tag".
Oh well. Replacing a checkpatch warning by a different checkpatch warning
is a really useful exercise.
Use the proper GPL-2.0 identifier which is what the boiler plate in the
file had originally.

properties
To comply with tests we need to support more power supply properties:
POWER_SUPPLY_PROP_VOLTAGE_NOW
POWER_SUPPLY_PROP_TEMP
POWER_SUPPLY_PROP_CHARGE_COUNTER
POWER_SUPPLY_PROP_CURRENT_NOW
POWER_SUPPLY_PROP_CURRENT_AVG
POWER_SUPPLY_PROP_CHARGE_FULL
POWER_SUPPLY_PROP_CYCLE_COUNT
POWER_SUPPLY_PROP_VOLTAGE_MAX
POWER_SUPPLY_PROP_CURRENT_MAX

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.
