Series ARM PSCI: Add support for vendor-specific SYSTEM_RESET2 | expand

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.

I would rather use param instead of type in the name.
