[RFC v2 1/3] dt: psci: Add arm,psci-sys-reset2-type property

[Elliot Berman]

Some implementors of PSCI may relax the requirements of the PSCI
architectural warm reset. In order to comply with PSCI specification, a
different reset_type value must be used. The alternate PSCI
SYSTEM_RESET2 may be used in all warm/soft reboot scenarios, replacing
the architectural warm reset.
