drivers/i2c/alps: Get rid of i2c/alps driver
i2c/alps driver implementation is an exact copy of the i2c/hid driver with only the addition of ALPS0001_HID. This can be supported by the i2c/hid driver using the hid field in devicetree which is what glkrvp mainboard does. So, this change removes the i2c/alps driver which is anyways unused.
