firmware: ti_sci: Unconditionally register reset handler

Browse Source 
There was once a limitation that there could only be one system
reset handler. 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.
