Remove <linux/i2c-id.h> and <linux/i2c-algo-ite.h> from userspace export

Do not export the following i2c header files to user space:

* i2c-id.h: These IDs are internal to the kernel and user space
  does not need them.
* i2c-algo-ite.h: The driver is broken and planned for removal, so
  let's not export it for now. The extra ioctl defined here can
  be standardized and moved to i2c-core/i2c-dev if really needed.
