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.

- * struct i2chid_platform_data - used by hid over i2c implementation.
- * @hid_descriptor_address: i2c register where the HID descriptor is stored.
- * @supplies: regulators for powering on the device.
- * @post_power_delay_ms: delay after powering on before device is usable.
- *
- * Note that it is the responsibility of the platform driver (or the acpi 5.0
- * driver, or the flattened device tree) to setup the irq related to the gpio in
- * the struct i2c_board_info.
- * The platform driver should also setup the gpio according to the device:
- *
- * A typical example is the following:
- *	irq = gpio_to_irq(intr_gpio);
- *	hkdk4412_i2c_devs5[0].irq = irq; // store the irq in i2c_board_info
- *	gpio_request(intr_gpio, "elan-irq");
- *	s3c_gpio_setpull(intr_gpio, S3C_GPIO_PULL_UP);
