Input: edt-ft5x06: prevent using on-stack buffer for I2C transfer

Using this driver with a DMA enabled I2C controller produces the
following warning (with CONFIG_DMA_API_DEBUG enabled):
|at91_i2c f8014000.i2c: DMA-API: device driver maps memory from stack [addr=8f847e29]

Prevent this by using a preallocated buffer.
