This feature is implemented on some systems using an IPMI OEM command:
https://github.com/openbmc/google-ipmi-sys#delayedhardreset---subcommand-0x03

It currently just activates the systemd target
gbmc-psu-hardreset.target and lets you register services to do the
actual hotswap reset (usually by toggling a GPIO). Having a unified
solution in x86-power-control for this would be great!
