On systems with SCP (running crust) scpi_system_reboot action
performs board-level (PMIC) reboot. This doesn't preserve RAM content
on A64 PinePhone at least.
warm/soft system reset without RAM reset is required to get
pstore (persistent storage) in RAM working with Linux kernel. That is
very useful for oops/panic logging for post mortem analysis.
scpi_system_reset action performs reset via SoC reset (using watchdog)
and RAM content is preserved in this case. Linux kernel detects
system_reset2 support and uses it for warm reset automatically.
