iio: adc: xilinx: Remove dead code from xadc_zynq_setup
This patch removes dead code from xadc_zynq_setup. The condition "if (tck_rate > XADC_ZYNQ_TCK_RATE_MAX)" cannot be true at any point of time. There is also an incompatible parameter used in the code. This patch fixes the same reported by coverity.
