arm64: dts: meson-gxbb-wetek: fix missing GPIO binding

stable inclusion
from stable-v5.10.94
commit 6edd1bd8e3d81d55d2cd00ffb44d55bdfb5a1d6f
bugzilla: https://gitee.com/openeuler/kernel/issues/I531X9

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=6edd1bd8e3d81d55d2cd00ffb44d55bdfb5a1d6f

--------------------------------

[ Upstream commit c019abb2 ]

The absence of this binding appears to be harmless in Linux but it breaks
Ethernet support in mainline u-boot. So add the binding (which is present
in all other u-boot supported GXBB device-trees).
