Due to that we only would register this handler when a non-standard device tree property was found, else we left the default handler in place (usually PSCI). Now that we can have multiple handlers, and TI-SCI reset is always available in the firmware, register this handler unconditionally. This priority is left at the default so higher priority handlers (like PSCI) are still attempted first.
