i2c_device_id::driver_data to 0
These drivers don't use the driver_data member of struct i2c_device_id,
so don't explicitly initialize this member.
This prepares putting driver_data in an anonymous union which requires
either no initialization or named designators. But it's also a nice
cleanup on its own.
While add it, also remove commas after the sentinel entries.

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new()
call-back type"), all drivers being converted to .probe_new() and then
03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert
back to (the new) .probe() to be able to eventually drop .probe_new() from
struct i2c_driver.

The probe function doesn't make use of the i2c_device_id * parameter so it
can be trivially converted.

Use devm_delayed_work_autocancel() instead of hand writing it.
It saves a few lines of code.

The driver includes two GPIO headers but does not use
symbols from any of them, so drop these includes.

We have a dedicated pointer for that, so use it. Much easier to read and
less computation involved.

Explicitly cancel/sync the irq_work delayed work, otherwise
there's a chance that it will run after the device is removed,
which would result in a use-after-free.
Note that cancel/sync should happen:
- after irq's have been disabled, as the isr re-schedules the work
- before the power supply is unregistered, because the work func
uses the power supply handle.

Call order on probe():
- max14656_hw_init() enables interrupts on the chip
- devm_request_irq() starts processing interrupts, isr
could be called immediately
- isr: schedules delayed work (irq_work)
- irq_work: calls power_supply_changed()
- devm_power_supply_register() registers the power supply
Depending on timing, it's possible that power_supply_changed()
is called on an unregistered power supply structure.
Fix by registering the power supply before requesting the irq.

If the driver is built as a module, I2C module alias information is not
filled so the module won't be autoloaded. Export the I2C and OF devices
ID to the module by using the MODULE_DEVICE_TABLE() macro.
Before this patch:
$ modinfo drivers/power/supply/max14656_charger_detector.ko | grep alias
$
After this patch:
$ modinfo drivers/power/supply/max14656_charger_detector.ko | grep alias

The MAX14656 USB charger detector, also known as "AL32" is used to detect
the presence and capabilities of attached USB chargers. The device is
attached via I2C plus one interrupt line to signalize events.
The device can be found in LG smartphones like LS665 and LS770, compatible
devices are present in 4th/5th generation Amazon Kindle readers referenced
in source code packages as "Maxim AL32".
The initial version of this driver has been extracted from LG source code
package LGLS665_Android_Lollipop_LS665ZV3, enriched with information from
the Kindle_src_4.1.3 source code package and adapted to the current power
class sysfs interface. Non-Standard Apple chargers which the device may
detect are mapped to the USB Battery Charging Specification Revision 1.2
class USB_DCP.
