base-files: armsr: add script to migrate GPIO switches on Ten64 board
Due to a change in kernel 6.2, the GPIO numbers on certain
architectures (including arm64) have changed. This script
will update any defined GPIO switches to the new numbering.
See https://lists.openwrt.org/pipermail/openwrt-devel/2024-March/042448.html
for more information.
In the future, the GPIO switch mechanism will likely be
replaced with something using libgpiod.
