[U-Boot] [PATCH] ARM: dts: logicpd-som-lv: Fix MMC1 card detect

The card detect pin was incorrectly using IRQ_TYPE_LEVEL_LOW
instead of GPIO_ACTIVE_LOW when reading the state of the CD pin.

Without this patch, MMC1 won't be detected.

This is the same patch submitted to linux-omap, but I was hoping
to get it applied to U-Boot without having to wait for the
linux adoption and then backporting.

Fixes: 5448ff33f281 ("ARM: DTS: Resync Logic PD SOM-LV 37xx
devkit with Linux 4.18-RC4")
