When present, configure the pin as input and use GPIO for card presence instead of SDIF_DetectCardInsert(). Useful if the board uses a pin other than SD0_CARD_DET_N for card detection. On the LPC55S28 we needed it to work around an issue where configuring PIO1_13 as SD0_CARD_DET_N stalled Flexcomm6 I2C transfers. The same pin works when muxed as GPIO.
