kernel/system: use libgpiod

[robin-reckmann]

• Use gpioset/ gpioget etc instead of the directly interacting with sysfs
• Keep a list of all gpio pin names in dts (to be filled in later PRs), so that a pin can be directly addressed by name in userspace.
• Remove gpio service, since setup of the pins is not necessary anymore.

TO DOs

• Confirm usb hub functionality on tizi
• Migrate power_drop_monitor.py to libgpiod
