mvebu: gl-mv1000: fix sdhci1 controller

GL-MV1000 external SD controller was broken by a recent kernel update
between OpenWRT releases 24.10.2 and 24.10.3 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.
