HID: i2c-hid: Add IDEA5002 to i2c_hid_acpi_blacklist[]

Users have reported problems with recent Lenovo laptops that contain
an IDEA5002 I2C HID device. Reports include fans turning on and
running even at idle and spurious wakeups from suspend.

Presumably in the Windows ecosystem there is an application that
uses the HID device. Maybe that puts it into a lower power state so
it doesn't cause spurious events.

This device doesn't serve any functional purpose in Linux as nothing
interacts with it so blacklist it from being probed. This will
prevent the GPIO driver from setting up the GPIO and the spurious
interrupts and wake events will not occur.

HID: i2c-hid: Switch i2c drivers back to use .probe()

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.

HID: i2c-hid: acpi: Drop unneded NULL check of adev

The driver is enumerated on ACPI platforms, so adev is valid.
Since there is no valid I²C ID table provided, there is no
possibility to bind a device to this driver via user space.
Hence, drop unneeded NULL check of adev.

HID: i2c-hid: acpi: Drop redundant ACPI_PTR()

The driver depends on ACPI, ACPI_PTR() resolution is always the same.
Otherwise a compiler may produce a warning.

That said, the rule of thumb either ugly ifdeffery with ACPI_PTR or
none should be used in a driver.

HID: i2c-hid: Reorganize so ACPI and OF are separate modules

This patch rejiggers the i2c-hid code so that the OF (Open Firmware
aka Device Tree) and ACPI support is separated out a bit. The OF and
ACPI drivers are now separate modules that wrap the core module.

Essentially, what we're doing here:
* Make "power up" and "power down" a function that can be (optionally)
implemented by a given user of the i2c-hid core.
* The OF and ACPI modules are drivers on their own, so they implement
probe / remove / suspend / resume / shutdown. The core code
provides implementations that OF and ACPI can call into.

We'll organize this so that we now have 3 modules: the old i2c-hid
module becomes the "core" module and two new modules will depend on
it, handling probing the specific device.

As part of this work, we'll remove the i2c-hid "platform data"
concept since it's not needed.
