Input: iqs7211 - point to match data directly
Point the OF match table directly to the struct that describes the device as opposed to an intermediate enum; doing so simplifies the code and avoids a clang warning. As part of this change, the I2C device ID table is removed, as the device cannot probe without an OF node due to the unique nature of the hardware's interrupt pin.
