I think this needs a description that explains what this is actually
for, and "boot-gpios" is not really an accurate name for what it is used
for IMO.
I was using the name `boot-gpios` since cc1352-flasher uses the name
boot-line. Anyway, would `bsl-gpios` be better? Or for more descriptive
names, I guess it can be `bootloader-config-gpios` or
`bootloader-backdoor-gpios`.
