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.
