arm64: dts: ti: verdin-am62: use SD1 CD as GPIO
TI SDHCI IP has a hardware debounce timer of 1 second as described in
commit 7ca0f166f5b2 ("mmc: sdhci_am654: Add workaround for card detect
debounce timer"), because of this the boot time increases of up to 1
second.
Workaround the issue the same way that is done on
arch/arm64/boot/dts/ti/k3-am625-beagleplay.dts, using the SD1 CD as
GPIO.
