arm64: dts: exynos: gs101: switch to gs101 specific reboot

Browse source

gs101 (Google Pixel 6 and Pixel 6 Pro) supports cold- and warm-reboot.
Cold-reset is useful because it is more secure, e.g. wiping all RAM
contents, while the warm-reboot allows RAM contents to be retained
across the reboot, e.g. to collect potential crash information.

Add the required DT changes to switch to the gs101-specific reboot
method, which knows how to issue either reset as requested by the OS.

The PMIC plays a role in this as well, so mark it as
'system-power-controller', which in this case ensures that the device
will wake up again after a cold-reboot, ensuring the full power-cycle
is successful.
