Subject: Input: add support for SuperH MigoR touchscreen

This is V2 of the MigoR touch screen driver. The chip we interface to
is unfortunately a custom designed microcontroller speaking some
undocumented protocol over i2c.

The board specific code is expected to register this device as an i2c
chip using struct i2c_board_info [] and i2c_register_board_info().

[dtor@mail.ru: don't enable touchscreen if there are no users]

Subject: Input: usbtouchscreen - ignore eGalax screens supporting HID protocol

The newer versions of the eGalax/EETI screen implement the HID protocol.
The device IDs are still the same, but the USB interface descriptor shows
the device being of HID class. Change usbtouchscreen to ignore the HID
models as they are handled properly by usbhid.
