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.
