arm64:dts:seco: Fix line-names of D18 GPIO-Expander
The line-names have to be assigned to the GPIO-Expander and not the I2C-Bus.
Dear all, On Thursday, 4th September 2025, we will test the new disaster recovery environment. A disaster recovery test will take place between 4:00 PM and 6:00 PM CEST. Please refrain from making any changes, as they will be lost. Once testing is complete, the production environment will be restored. Thank you for your understanding.
The line-names have to be assigned to the GPIO-Expander and not the I2C-Bus.
