    mvebu: gl-mv1000: add devicetree patch for sdhci1
    
    GL-MV1000 external SD controller was broken by a recent kernel update
    due to a mistake in Device Tree: "regulator-gpio" was defined without
    required "gpios" property.
    
    Removing this regulator definition from the device tree fixes this issue
    without any side effects so far.
    
    "main" branch uses upstream devicetree for this device, so add a kernel
    patch for the "mvebu" kernel family.

+Subject: [PATCH] arm64: dts: marvell: fix sdhci1 controller for gl-mv1000
+
+GL-MV1000 external SD controller was broken by a recent kernel update
+due to a mistake in Device Tree: "regulator-gpio" was defined without
+required "gpios" property.
+
+Since "no-1-8-v" property is also defined for this controller
+a switchable vqmmc-supply regulator performs no function - a fixed 3.3V
+IO voltage will always be used.
+
+This regulator definition was probably added by mistake from a Device
+Tree from another device.
+
+Remove incomplete vcc_sd_reg1 regulator definition to fix this issue.
