[U-Boot] [PATCH 1/2] ARM: dts: logicpd-som-lv-37xx-devkit-u-boot: Remove unused GPIO
The only GPIO bank needed in SPL is GPIO4 and the SPL space is tight.
This patch removes the all but GPIO4 from the spl device tree to reduce the SPL footprint.

The SPL is too tight, and it cannot start any longer. To help reduce the size of SPL, we need to remove some non-critical features.
This patch removes SPL_GPIO_SUPPORT to free up some operating space.

Applied to u-boot/master, thanks!
