base-files: gpio switch: add named GPIO support
Previously, gpio_switch only accepts GPIO pin number as input. Once a GPIO pin is exported and named by device tree, its pin state cannot be configured and saved across reboots by UCI. This patch adds support for named GPIO pins. Thus GPIO pin can be exported by device tree with active high/low correctly configured, having human-readable name in /sys/class/gpio/ is also now possible. More importantly, GPIO pins which are referenced by name will be immune from pin mapping breakage while unintentional pin number changes are introduced by kernel or driver updates.
