ti: k3: drivers: ti_sci: Update ti_sci_msg_req_reboot to include domain

The ti_sci_msg_req_reboot message payload has been extended to include
a domain field, and this should be zero to reset the entire SoC with
System Firmwares newer than v2020.04. Add the domain field to the
ti_sci_msg_req_reboot message structure for completeness. Set it up
to zero to fix the reboot issues with newer firmwares.

This takes care of the specific ABI that changed and has an impact on
ATF function.
