arch/arm/src/imxrt/imxrt_lpspi.c: Remove hack setting LPSPI1 daisy irrespective of pin config. I assume this hack pre dated the addition of the dasiy chain setting. It was forcing LPSPI1 pins to read from selection 1 irrespective of pin config. The correct input selection is done in imxrt_config_gpio.
