drivers/i2c: Use I2C HID driver for wacom devices
Wacom I2C driver does the same thing as I2C HID driver, other than defining macros for Wacom HID. Instead of maintaining two separate drivers providing the same functionality, update all wacom devices to use generic I2C HID driver. BUG=None BRANCH=None TEST=Verified that ACPI nodes for wacom devices are unchanged.
