rockchip: dts: rk3399-puma: add /config/sysreset-gpio property
On the RK3399-Q7, we want to trigger a full platform reset (so the various software stacks supported don't have to deal with the same complexities over and over again) in case that anything other than a power-on reset occurred. To do so, this defines the /config/sysreset-gpio property and has it point to a GPIO that will perform a power-on reset of the entire platform.
