arm64: dts: meson-gxbb-odroidc2: fix GPIO lines names

BugLink: https://bugs.launchpad.net/bugs/1857158
[ Upstream commit 2165b006b65d609140dafafcb14cce5a4aaacbab ]

The gpio line names were set in the pinctrl node instead of the gpio node,
at the time it was merged, it worked, but was obviously wrong.
This patch moves the properties to the gpio nodes.
