Only DT based probing is used for the Motorola CPCAP charger driver, so
drop the !CONFIG_OF parts and redundant of_match_device() call.

Depend on the explicit SoC defines rather than generic
architectures like most of the rest of the HW drivers do.
This makes the drivers only available for the HW and for
compile testing.

At the beginning of the probe function, "charger->dev" is set equal to
"&pdev->dev". Therefore it's more clear to subsequently use "charger->dev"
instead of "&pdev->dev".

Currently the struct "rt5033_charger_data" is initialized rather complicated.
The cause lies inside of the struct "rt5033_charger", where struct
"rt5033_charger_data" is implemented as a pointer *chg.
Therefore, inside of struct "rt5033_charger" change the struct
"rt5033_charger_data" to non-pointer "chg". It is then initialized right
away and can be accessed more easily.

Implement cable detection by extcon and handle the driver according to the
connector type.
There are basically three types of action: "set_charging", "set_otg" and
"set_disconnect".
A forth helper function to "unset_otg" was added because this is used in both
"set_charging" and "set_disconnect". In the first case it covers the rather
rare event that someone changes from OTG to charging without disconnect. In
the second case, when disconnecting, the values are set back to the ones from
initialization to return into a defined state.
Additionally, there is "set_mivr". When connecting to e.g. a laptop/PC, the
minimum input voltage regulation (MIVR) shall prevent a voltage drop if the
cable or the supply is weak. The MIVR value is set to 4600MV, same as in the
Android driver [1]. When disconnecting, MIVR is set back to DISABLED.
In the function rt5033_get_charger_state(): When in OTG mode, the chip
reports status "charging". Change this to "discharging" because there is
no charging going on in OTG mode [2].
Yang Yingliang detected missing mutex_unlock() in some error path and
suggested a fix [3]. The suggestion was squashed into this patch.

their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS

power_supply_uevent() which is called to emit a udev event on device
deletion attempts to use the power_supply_battery_info structure,
which is device-managed and has been freed before this point.
Fix this by not generating all battery/charger properties when the
device is about to be removed. This also avoids generating errors
when trying to access the hardware in hot-unplug scenarios.

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 .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.
